throttle

Hey everyone, I have an interesting issue that I'd love some feedback on. I have a 2005 LJ, non-rubicon, 195,000 miles, with the 42RLE automatic transmission. I'm running into an interesting issue where the engine will have a very small moment of almost stalling when hitting the throttle at...

Hey guys I’m not sure how to word my question other than after I drive my 98 TJ for about 20 minutes on the highway if I stop somewhere or at a light or drive thru my RPM’s go way down to the point of stalling and when I push on the gas it doesn’t rev. It only happens when I drive it a lot that...

I have a 1998 wrangler Sahara that stalls occasionally in neutral or when my clutch is in. Typically, this happens when cutting it hard in reverse, after I take it out of reverse, but it can also happen when I am stopped. The RPM’s are very variant at idle, they fluctuate between 7-800 up to...

I then engage cruise control and the gas pedal locks into place (I'm assuming this is supposed to happen) but the throttle does not lock into place. The engine simply idles and I gradually slow down because I'm not actually...

I can't seem to win with my TJ. Just fixed a few issues and now I'm throwing a p1604 code. This is a communication issue apparently with the computer. I just completely removed and cleaned my throttle body and IAC so I'm thinking something during that processes may have caused this problem. The...

so today I took on the task of cleaning my throttle body. As usual I have to take it to the next level. I pulled the butterfly valve and set screw that hold the plate open just enough for idle. Now I have no clue what the gap needs to be between the butterfly valve and the throttle body. I...
