On my V6 i have been having some intermittent stuttering at speed. Finally i have a codes that popped up a 44 and a 32.
Im thinking these are both just effects and not the cause, but would appreciate some direction to head to next.
Fuel pressure seems ok in the driveway ( i need to find a way to view pressure while driving.. ). Under acceleration and around town the car works fine, its just while cruising in 5th for a few miles do i start seeing the problem. Idle is ok, so i don't think i have much of a vacuum leak ( the 32 ) and i wouldn't think a blown O2 sensor would cause intermittent problems...
The only thing I can figure, would be a problem due to the MAP sensor. If the car accelerates perfectly, then it's not a fuel issue. When the car is in 5th gear and it's cruising, it's not really using that much fuel. I would verify that the MAP sensor is still ok.
A code 44 means the engine is running lean, and I believe 32 means O2 sensor.
What kind of O2 sensor are you using? I've found that the ONLY ones that actually work, are the AC Delco and BOSCH units.
Hope that helps some?
