SORRY ...MAYBE I SHOULD HAVE SAID HIGH..IT IDLES AT 2G
AT START UPS PARK AND NUETRAL

itschristorres8 · October 11th, 2006, 09:32 PM

2g?

....2000rpms?

most likely a computer problem and its reading something wrong

also caps is not need for every letter...

2000 rpms is way high, someone had this problem a lil while ago and went to a place, i bet its the ECU reading somthing wrong

itschristorres8 · October 11th, 2006, 09:39 PM

no prob, find a place that will do computer work on the car

im not 100% sure thats it...just 80%..i dont see what else it could be

its not oil, any kind of filters or w.e

try cleaning your iac valve first also check for vacuum leaks before you go spend a bunch of money

99mustang232 · October 11th, 2006, 10:44 PM

does it only idle fast on startups, once it is up to temp what is the idle rpm? does it fluctuate at all? fast/high idles can be a problem of vac leaks or airflow related sensors. do you have a CEL showing, go to your local autozone and get them to scan it for codes, it is free. they will plug in a handheld and scan via obdII port and tell you a code that you can post here. do you have an aftermarket oilable airfilter, sometimes over oiling will cause MAF issues. you can try looking at your IAC. did you do any recent mods, look over the vac hoses and snoop around the intake manifolds to see if you have a leak in the gaskets?

AtlanticBlue99 · October 11th, 2006, 10:58 PM

if the idle fluctuates, you probably have a vaccuum leak somewhere in the intake tract. if it is just high, it could be a bad IAC or a few other sensors. ideal idle for an auto is 900rpms in P or N, and 800 in D or Gear

could cause a fluctuating or high idle too

99mustang232 · October 11th, 2006, 11:14 PM

could be stuck, from buildup

chrish91286 · October 11th, 2006, 11:17 PM

the IDLE AIR CONTROL valve adjusts the throttle plate at idle. if the spring inside is stuck, has debri in it, gummed up it will cause a varying number of problems. it might not be the iac it could also be a vacuum leak like i already said
