Crazy Idle problem

I have replaced my fuel pump recently, I also have put a complete new injector rail on the car. The car is in perfect timing and runs well except for the thing is sometimes it will not idle correctly, it will surge and then just die. Seems like if I turn the ignition all the way off and then restart it it will start up and idle fine again. This happens intermittantly and has been going on for a while now and I cannot figure what it is. Anyone has some insight on what may cause this? Thanks.

Pull the codes and check the TPS for initial setting and flat spots/drop outs. There are "how to" articles in the Technical Articles.

Also clean the IAC (idle air control) the cylinder like thing on the back of the throttle body. Take it off and spray it out with carb or brake cleaner.

Thanks for replying

I have this problem with my TC, the problem has gone away(for now) after i pulled the idle air control and blew off the connectors and the sensor it's self. this problem could also be an air intake leak, i also had this problem. the easyist way to check that is it take your air filter cover off take out the air filter and cover the air intake with your hand, if the car still runs you deffinalty have a leak, if it stalls you dont pritty simple way to check
