2000GTX
Well-known member
Hey guys, I bought my GTX from wowzer with the knowledge of it having a bad IAC. I replaced that nonsense, then the check engine light kept coming on and it turned out to be the MAF and the TPS. So I replaced both of those things, and I'm STILL having issues with the idle. When I start up cold it idles real high at like ~2500 and as it heats up it does the same idle hunting that it used to do when the IAC was bad. Once it heats up completely it idles completely normal. What on earth could possibly be wrong with this thing? Hopefully I explained it well enough. Just in case, here it is again:
Cold start: high idle ~2500 RPM
As its warming up: Hunting Idle that slowly drops to normal idle speed
Completely warmed up: Pretty much normal idle
Parts replaced so far:
Mass Airflow Sensor
Idle Air Control
Throttle Position Sensor
Hopefully one of you experts know what I could try next, because I don't know what to do. /ubbthreads/images/graemlins/banghead.gif
