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..

Tugged on all the wires while running and it doesn't phase the engine. Also took a spray bottle and sprayed water on all the wires i could get too, again no effect.

The only electrical that isn't right that i know of, is the ODBC connector, it doesn't seem to connect reliably to my laptop, preventing me from recording data while moving ( going to get another one next week ). While sitting still with the engine off it normally connects, start the engine or bump the cable and it disconnects.

Doesn't seem weather/temp related either.

Somedays it runs just fine and gets in the mid 20s for mpg.

Its been like this for a while, but since i had a 2nd GT as my daily i didn't want to mess wit it much until it got warm. However, the daily driver GT is now gone, and id really have to figure it out now.

Does have new coil ( it was shorting ). but didn't make any difference on the stutter. Replaced the ECM due to a no start after an engine swap over a year ago. ( never did figure out the real problem, after starting a couple of times, it quit.. then it just started to work one day... ).

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?

Donno what kind the O2 sensor is, its been there since i got the car. I have another MAP, i can swap that pretty quickly and see what happens.

EDIT: Well a new MAP and a short test drive seemed ok... But somedays it worked fine anyway, so ill know for sure in a couple of days. Ill cross my fingers it was that simple
