my idle is out of control

[jtimcho]

hey guys how are you. well heres my problem. my car can't hold idle after it warms up. sometimes it is perfect and other times it will drop to zero and then back up over and over. plus it feel like my car has no torque. i have replaced all the vacumm lines i could fine and every sensor,iac motor,tune up. any ideas on what could cause this and how to fix it. thanks

I would be checking for vacuum leak(s). Mine was similar when it was cold it would die if I did not rev and the idle was all over the place as it warmed up. Sometimes it would idle around 800 RPM and as it warmed up it would jump to around 1100 RPM. Ended up being a bad hose that ran into the upper intake. Hard to see because the leak was actually under the intake.

Good Luck
