I will get some pics.

Yeah, when really looking in there, I though the same thing. Unless I find some major corrosion when disconnecting that larger wire cluster at the connector.... I can't really see any big issues there. Certainly nothing that would cause such a drop in idle.

Try this experiment; see what happens to the idle when you press on the switch the brake linkage/pedal activates for the rear lights.

Yes, good idea. I will try that first thing. The brake depression seems to be the most dramatic, fairly equal to the combined load of the High beams and turn signal.

And, FWIW, I'm leaning towards a way of hopefully disconnecting the entire chassis electrical system to take it out of the picture, then see if that has any effect on your idle. This may not tell much, but hypothetically speaking, if it does affect things positively, you'd know if was related and have more of a specific area to troubleshoot.

Yeah, I remember you saying so. Thanks for investigating, either way! I was thinking there might be a way to test at the ECU for voltage to the injectors, or other related, crucial items. Not sure how I would go about that.... But I would assume that I could simply test at the No10 and No20 connectors against the E2 and watch the voltage as I apply the brake(after, of course, checking at the brake switch, itself, first) lights and signal.

And, yeah, nothing's conclusive, so you just have relax and let the guidance be there. You wanted to learn all about these things, right? I suppose this is a good way to do it....haha!

I've pm'd a friend who might be able to help in regards to chassis/EFI connections. Hopefully, we'll hear from him, soon. If not, I'll explore other avenues.

Today is the first of many days for hay hauling. We've got 8 round bales ordered and it's gonna take several trips to get it all home since I can only haul one at a time in my trailer. That's all the weight any of my 4rnrs can manage, anyway. Needless to say, it's going to be a dirty, sweaty week. Whew! Life in the country is pretty good, though. Cooled off last night with some iced lemonade spiked with Lemoncello. Ahhhhh.......so good!

Thanks, Mark. Jus' me bein' me.........

Yeah, of COURSE I am really enjoying learning this stuff,...you know that, fo sho! lol. I just get, well, 'LONGING'(for lack of a better word, lol) in regards to figuring things out. I'm not used to anything taking me out for this long....but then again, MOST THINGS DON'T HAVE 3,438 VARIABLES! hahaha. Ok, I exaggerated, lol. Bout 200? lol. Anyway, I'm looking forward to burying this gremlin, ..DEEP! lol.

Oh, aren't we all????? BAHAHAHAHAHA!!!! I'm just pulling yer leg, man. I had to throw that in there, ya know? Were it not for gremlins, we wouldn't need our trusty Ohm Sabers. And, what would life be without that? <<<<ehem>>>>> BORING!!!

I know it's only been leaking in the Driver side of the cab/back of rear firewall, because when working on the ECU, i've NEVER noticed any moisture, at all. To be honest, it doesn't feel like brake fluid, Matthew.... That concerns me, because, I now wonder what 'coolant' related Item could be leaking into my cab??? I've never buried it in water(not that deep, but definitely up to burying the gas tank/up to the collector to the original exhaust.... NEVER sitting though, just driving through. And, well, I'd think that would've dried by now, ya know? The heater core .....could it be leaking right there? I thought it was toward the center... ???

Trust me. If it were coolant leaking, you'd smell it. Particularly as warm as it is right now. When I had a leak in that area, it was the clutch MC. Been watching the fluid levels at all?

Thanks for asking your bud,...Hope he chimes in. Appreciate it!

Yeah, well so far he hasn't. But, he has a life, I would think. If nothing in the way of a reply occurs by tomorrow, I'll ask around some more.

PS> I serve Sparkling Muscato-Lemon- Bellini on the rocks with slices of Meyer Lemons off my tree out back, all the time in the summer. I mentioned the Santa Rosa Sugar Plum Bellini's not long ago.... "SIMPLY, THIRST SMASHING EXPLOSIONS OF FLAVOR, GOOD MAN!" they tell me, hahahahha.

You don't watch your orchards at night, do you?

PSS> Best wishes with the Hay, ...careful there, Bubba! lol.

Actually, I've had one of them suckers roll off the trailer almost over me. Fortunately, I have cat like reflexes. Ever seen "Crouching Tiger, Hidden Dragon"? You remember the girl catching the tea cup before it fell off the table? Yeah, those were really my hands!!!!

DANGGGGGGGG, I NEED TO GET , FAST!(minus the companions until I get there, lol... I always make like 10 new friends) Think I will, this week some time. NO, in fact, YES, I WILL, ....I'm going to head out there and clean up/dust off my gear, assemble my hitch-carrier, go grab the cooler I've been dreaming about at BIG5, a 100qt., ....ON SALE FOR 59$!!! , load up my new CHAIR(FINALLY found the most comfortable second chair for camping--I have an Anti-Gravity chair, but not good for sitting up and such-- The new one has a Hard, Hinged table built on the side with cup holder and DOES NOT cut into the legs, ....Good padding, every accessory-pocket on the side...STOKED!:d:d:d...... Toyoholic sat in it.... it's SWEET! lol). I've been wanting to get a console from Pepboys that's on sale. Have to measure it out, ...they're REALLY nice, with cooler(9 cans) and 4 Power outlets) for 49$!! Hmmmm. lol OOPS, they're calling, time to feed the Peeps!

'Bout time, chief. Get that cooler and then you'll have absolutely no excuse not to go! BTW, how long will you be gone? And, will there be anyone watching the orchards for you during this time? Just curious.....

Ok, here's the deal, most recent;

I thought I'd already mentioned this on here, Thook....but here we go, "MY BAD", lol...>>>

When cruising around town with my new Yotatech Brother, Yotaholic(that is, when we weren't sitting at street lights for 5 minutes, ...EVERY OTHER BLOCK! hahaha).. We finally came to a stop in a parking lot after screaming down the freeway and bit and such, ....and sat there, idling, for several minutes. At one point, I showed him something I'd noticed, lately. Well, I've always noticed it, partially(dimming and voltage needle jumping a tiny bit), but not related to idle speed....>>>>

1. When idling at 750-800-RPM, parked, if I put on the turn signal, I noticed that the idle dropped some.(Maybe 35-50rpm).

2. Then, while idling, turn signal engaged, I turned on the headlights.... The idle dropped even more(around 75-RPM, total)

3. Then, with Turn signal and headlights on, I hit the brights, ..... The idle dropped even more(A total of 100rpm with all three items on).

4. Today, while fiddling around with this some more, I warmed up the truck. I then went through this battery of 3 things and found NEARLY the same results.... The truck wasn't as warmed up, seeing as I'd only driven around the block.... but it WAS at Operating temp., completely. So, with all 3 items pulling power, the idle dropped around 75RPM... I then turned on the stereo and cranked it a bit(to pull more power than just on position) and it dropped even further to around 125RPM total).

If any of you are still interested and are following, hahaha, ... If you remember, I was thinking that I had an issue with my booster, as when I'd depress the brake at times, the idle would drop some. Now, I know, when pumping it over and over, it's going to pull a large vacuum away and the idle can drop a lil bit(tested it on other cars). HOWEVER, .... I never thought of the fact that both brake lights are also pulling voltage... DEFINITELY more than a turn signal, no? ....At least, I would think, Equal? After all, those bulbs are dual element..... does that make any difference? Either way, in many cases where I was at a stop, tripping out on what I thought was the booster issue, ...I'd also had my signal on! HMMMMMMMM! So, what I'm getting at is this; It would make sense, wouldn't it, that when I was thinking that, before(booster), and I had my foot on the brake and the signal was on.... That my idle was dropping out on me a lil bit. When I'd take my foot off the brake... VOILA, it would come back up.

Two other things that MIGHT not be related, but WTH, I'll mention them.

1. My Right of column arm(Wiper, Cruise Control and Washer fluid button on the end)????>>>>> The washer fluid button has NEVER worked. It's always been depressed inward and will NOT come back out.

2. My power antenna motor works(it's the kind that I believe you have to actually press the button to raise it or lower it...1987)... BUT, the metal part, about 5/8 of the way down is separated from the body(or whatever it is) inside. Yesterday, when Yotaholic was trying to help me investigate this voltage thing, further, he pressed the button to raise the antenna and it flopped on the side of the truck(Sorry Jess......I should have told you it did that, hahaha... I'd forgotten). It doesn't fall on the ground....the nylon chord in there is still attached, INSIDE of the wand shaft(???).>>>>

The reason I mention the antenna thing is partly because i want some info on how to fix it, how easy is it to get rid of the power one and put a whip on there or something(do I want to do that or is it better to have the power one?)... and because, when first putting on my truck, you've all heard the buzzer on my videos. However, I've always had the radio off when doing those videos... What happens is; When turning on the car, if the radio is on, set on AM RADIO(doesn't do this on FM)... The key reminder buzzer in the dash interferes with the AM radio and you can literally hear the buzzer in the speakers until it clicks off. I don't really have much noise pollution, even with AM, otherwise(you know, driving around, engine RPM, etc.)...but does anyone know why it would be doing that? Just noise interference from the buzzer? Does anyone else have to deal with that?

Thanks guys, I'd really appreciate any guidance on this, from here on in. This could be leading me to something within my chassis electrical or otherwise that has been the source of my problem, all along. (or at least part of it, ya know?). Would any of you with smooth running/idling 22re's mind testing that out a bit, regarding putting a voltage load on like I did and record your findings for me, mentally? Give me a shout out on them, so to speak? PLEASE? LOL.

Thanks,

Mark

If so it sounds like the mast has seperated from the lower section that keeps it in place. If you need to replace it remove the chrome nut and raise the antenna holding it and you will be able to pull everything out with ease including the nylon cord. Notice which way the teeth on the cord are facing when it comes out. It's no big deal just makes it easier going back in. Insert new mast and lower the antenna while someone holds the mast and guides it in. If you didn't notice which way the teeth were facing either they face forward or backward. If it does bite facing forward turn it 180.

THANK YOU!

The next time I drive my 86 I will check for RPM drop due to electrical load.

ANDDDDDDD, ....Thank you again! lol.
