I've read a few posts with similar problems but nothing that quite matches.
I have a 02 GTP slightly modded. CAI, 3.4 pulley, removed u-bend down pipe, a ZZP 1.0 PCM, Borla Exhaust.
I recently replaced the water pump and it ran for several days with no issues. The problems started 3 days ago.
Here are the symptoms.
When starting the car the idle is normal (900ish) with an ambient temp of 25-34º. As the car warms up the idle increases reaching 2,500-3,000 when the car is at running temp (185-190º)
This is what I have tried.
I checked all the vacuum lines and nothing looked broken/cracked. I unplugged the MAF started the car and let it run for a minute then plugged it back in. (saw this in a previous post which did nothing) Using Torque and a BT OSBDII adapter I could see throttle position registering .04 without pressing the peddle and gradually increase to 100 when the peddle is pressed to the floor.
Does anyone have an information on what the vacuum should be at normal idle with the Torque app?
I'm looking for some help with what to try next or look at.
Thank You.
Kurt
