If you happened to be on TIS and say.......downloaded everything you could find for a 1992-1994 lexus sc400 and emailed it all to dntsdad@comcast.net, that would be cool.

 

That would've been cool! sorry man my account was just a two day and ran out on saturday

 

[GVIDEO][/GVIDEO]Haha ya no problem. Just kickin around a 1uz swap in my mind and wanted to check out some wiring diagrams.

 

Progress! got the last plug in and it works!!! starts up fine and runs like nothing. but it has a crazy high idle, no tach yet but it feels like 2.5-3k. Quite confident that its wired correctly now! (Although still completely possible it isn't)
What kinda stuff results in this high of an idle?
I AM still missing the Vapor Pressure Sensor, but it seems way high

Still pumped though!! sounds great!

 

High idle is basically sorted (Vac lines.... mostly) Now all that is left is a small coolant leak somewhere, Nearly ready for a rip!

 

Alright! Painfully close now! everything seems to be working well, no more leaks, holds temp, idles nicely, ect.
The only thing is that it doesn't idle down very quickly; if i stab the throttle it'll hold that rpm for a bit and slowly go back to idle...
Vac lines? feels like Vac lines.

 

How long does it hold it? Cables on throttle body adjusted correctly and moving freely?
Could be vacuum lines too.

 

i was worried about the throttle cable cause it does bind a little but the throttle seems to come to a complete close quickly.
Also, I have the EVAP hoes off the VSV to get it to idle cause it isn't wired in yet (Plugging that hoes gives me that high idle)
It only holds it for a second but its takes a while to idle down again

 

So this is how it sounds \/(Actually my engine)\/

 

Sounds pretty normal to me.

 

yeah maybe i'm being paranoid, i always get this way right after a build. I really need to hook up the tach to put my mind at ease!
Thanks for the help!

 

so i ended up wiring the the sensor in
Black(heater) -> B+
Black(heater) -> E1
White(signal) -> OX1
Blue(signal ground) -> HT

I don't know if that is right or not but my problem is the same, starts and runs great; but as soon as i try to push it a little the mixture becomes rich and the engine bogs down/dies.

What else could cause the mixture to go so rich like that?
outside of actually driving; the engine seems to run perfectly....
