try replacing spark plugs, PCV valve and all other normal tune up parts. Also try cleaning out your throttle body. I had the same problem when I first got my car and when I cleaned out the throttle body it seemed to help alot.

re- do your fuel s**t....pump, filter, oil, injectors, plugs and wires, air filter, and get that spray to spray into your mani while the car is on. also, spend some money to run mid grade in that s**t. i did all that and my s**t idles AT 720RPM, VERY WELL, and very quiet too. also, does it sound like its running tht high? if it doesnt, it may just be your tach thats off.

the problem started when i took my stock intake manifold off and got a skunk2 intake manifold.it just idles from 1 to 3,5 and you can hear it idleing like taht so i dont hink the tach is the problem. i have dsm 450cc bluetop injectors ..i also cleaned out the iacv and that didnt help i got the tps set to 5 volts

ok so i checked the seals around the injectors they wre bad so i changed them out then i changed out the tps and got it to 5 volts and the car still idles the same..my car is throwing a code 41 which is a map sensor i think .but would a map sensor make it idle like that

Code 41 points to a problem with the primary O2 sensor or its circuit. This possibly could explain the idle problem, although a more likely explanation is an intake air or vacuum leak.

spray brake clean on your intake manifold gasket. if the car studders, you have a vacumn leak. my guess is you have a leak. dont listen to these people who say start replacing fuel pump and all that s**t.
