Newbie with Idle problems

Hello guys! Just bought a '95 Laredo 4x4 I6 that idles around 500rpm, which is pretty rough feeling, if I tap the gas and get it to 1k rpm, it falls down to 700rpm and purrs like a kitten, then in a few seconds falls back to 500rpm. I read something about adjusting the TPS to DECREASE idle speed, can I do the same to increase it? Any ideas? Thanks in advance!!

I was having a similar problem with my 97. I replaced the idle control valve for $39 and it runs like new now. Good luck.

my 97 did almost the exact same thing and i changed the throttle position sensor and that fixed it. when i changed it i didn't see any way of adjusting it, maybe it is diferent on a 95.

Check the motor mounts too (trans mount also). this is a common problem.

to adjust - loosen screws, just a little, and twist it. you'll hear the idle go up or down. i have adjusted mine. don't loosen them completely. just enough to where you can TAP it with a small hammer or the backside of a scewdriver.

Hi there - Just bought a 93 ZJ and am having similar probs. Only in my case, idle speed drops (and occasionally it stalls) but only after the engine has really warmed up. Cold idle is purrfect. Any thoughts?

Thanks in advance - MJ
