2G Car will not Idle (not the TPS)

[Lavery]

Searched the threads and nothing seems to be similar to my situation.

Heres the issue. The car will not idle while moving. If I am driving and i push the clutch in and coast the RPMs will drop to 0. Theres no hesitation, it doesnt even try to idle. My boss ordered me a new TPS so i just put that on and it still does the same thing.

Also it only happens when the car is warmed up. I just let the car sit out there and Idle for about an hour after i put the TPS on and it did fine. But as soon as i put it in reverse to get it out of the garage it started acting up again.

Any help would be great, its supposed to snow out here tomorrow night so im trying to get it road worthy before then.

IAC?

Good luck.

Check base timing, ICS, BISS adjustment, vacum/boost leaks, and idle switch.

BTW - did you adjust the TPS for the correct voltage output, or just toss it on there?

He's at work right now, but he just text me and said he just threw a new TPS on... Didn't do any adjustment.

+1

Without the TPS correctly adjusted for where the IPS switches the ECU won't know that the throttle is closed. Dieing after the car warms up is a sign that the BISS and ISC/IAC aren't doing their jobs.

Thanks guys, I'll let him know.

I'll do the adjustment and report what happens

We did the adjustment of the TPS and also checked the IAC. Turns out that the IAC was bad. It read 29.5 Ohms on prongs 1-5 and 300+ohms on prong 6.
