Problem:
Looping cold idle, after warm up while driving or coming to stop if clutch is pressed car stays idled around 2500-3000 and then slowly comes down after 2-3 min. but then can't find idle. When viewing PIDS on scan tool calculated load is between 40-55 with no loads on. Hooked up vacuum gauge and at idle after warm up is only -10. O and my fuel mileage has dropped to 18 hwy.

Things i have tried:
Replaced all vacuum lines including PCV valve and houses.
Replaced intake boots with C-F-M ones.
Inspected all of intake for cracks and did smoke test.
Cleaned MAF.
Replaced both o2 sensors.


If any one has any idea whats wrong with my baby please let me no. Its driving me crazy that shes not running right. Plus i'm fixing to buy a turbo kit and i want this fix before i start.

Sounds like either the MAF took a shit or the TPS is dead.

TPS - sweep test
MAF - watch the #/min and see what it tells you. Stable, rising with throttle?
