hi...my 91 4runner 4wd v6 is acting up....when lightly pressing the gas i feel some shakeing and power jerks then goes....nothing to bad but really a concern......between 50 and 65 when lightly pressing the gas...feels like the back of the truck shakes.....my be an intake issue or spark plug issue....i keep the engine in great condition...anything you can think of.....same issue in my 240sx it's an 89 single cam and it does that a bit also

 

Try a different gas station. Fill it up and run some 93 octane thru it and clean your throttle body. It wouldn't to run some injector cleaner at the same time. Mine did the same thing and this fixed it. Now I only run med or high in it.

 

i've always put in 91 in CA we only have 91, 89, and 87....but the last month i've been puting in 87 gas in......i will change it and use injector cleaner....thanks for the shocks by the way...ome the only way to go....i had to toss those pro comps.....the only worry i have about ome is the travel is stock and my pro comps are 2 inches longer....i have not hit the dirt yet with them...hopefully today if the chick is not PMSing.....i will look into triming the bump stops also to gain travel...is there a good place to get good a arm bushings....one of mine i just changed is broke and the a arm is moving out ward

 

Glad you are happy with the OME's. You say you just replaced the bushing and they are broke already. Let me ask you did you put a rear truss bar on the lower control arms? They tend to spread and put alot of pressure on the bushings, not to mention the alignment always getting knocked out. You can order those from Barb at info@trdparts4u.com.

 

Did you check your fuel pump? Sounds like an issue of fuel starvation, and your engine is not getting enough fuel.

 

Another thing you can also do is to get under and feel for any play in the drive line.
Well that's my 2 cents. Let us know what you find out.

 

help my 91 putts....at idel it putts and the engine shakes.....not sure if its spark plugs or wires or exaust cat clogged finally or what....anyone know....someone told me gas but thats not it...putting just started....step on the gas and it drives fine just slower than normal....go to be plugs any way to check if wires are bad or plugs????

 

is there a tool for that??????

 

Use a Multi-meter set the meter to OHMs and check your readings......different length wires will have different reading.

 

thanks, i had drive line issues before...very simaller i will check it out....i got a new fuel filter but have not changed it yet i will.....rear trust bar...i just asked barb....some other people think its a spark plug issue or plug wire????

 

i guess i need a tool like that?????? i will look into it
