I was reading through this thread https://dodgeforum.com/forum/1st-gen...elerating.html and Im kind of experiancing the same thing. What im thinking is my U-Joints because recently it started making the "humming" noise he's talking about in that thread. You can feel the hum almost like a vibration. I looked at the U-Joints (1991 2WD by the way) and noticed the front one moves up and down some what and has alot of play rotating it. When I hit 65+ mph I can feel a hard vibration, which i think is the driveshaft so I am replacing those u-joints this weekend. Im also going to check out the rear end for fluid and, if needed, replace it. What kind of Gear oil should i get weight wise?

but the important question is





The bolt on the IAC, should it move while running? I know its suppose to move back into the IAC but should it twist side to side? Ill post a vid eventually if im not making sense lol

 

sorry for the huge pictures, cant figure out how to resize with photobucket without doing individually on my comp. forgot also, could that be causeing the really low idle at start? I cant reach in and start it on the first try and on the second the RPM's are at like 100...not 1000 but 100 until i hit the gas and let off then it goes to normal

 

My guess is that the bolt is only for fine tuning. But I don't know much about the LA's.

 

might be, i played with it and now i can start it without touching the gas, might play with it some more....and other things now that i got a job...damn economy!!! lol
