check your tps voltage with a meter; if it's off, loosen tps screws & move it around til meter reads 1.0

sounds to me like one of the hoses isnt plugged in all the way, theres 2 on the air tube, and 1 on the back side of the plenum. Theres a few other wires to plug back in as well, check em all.

Sounds like a common problem. It takes the computer about a week to figure it out. Reset your computer, and it might speed up the process.

Check the voltage on idle too. It should read 0.99 volts when the car is running. On my car it was the bottom 2 wires.

thanks for the input. I reset the comp. and will recheck the tps voltage. it seems a little better after driving a little tonight though. the service engine light just came on though.

Check the TPS. Thats 9 outta 10 times what causes the idle problems.

I had the same problem. Took my car a little while to re-learn everything. Check your TPS as well.

Reset your computer and check your TPS

How you reset the computer?? Just by removing the negative wire from the battery or there is a different way?

Pressing brake! I thought you only remove the negative wire and start it again. Btw should I leave the car ON after resting the computer for 15 min or no need of doing this? Thanks a lot buddy.
