hi all. I don't know if I'm posting this in the correct section but, here goes.
I have a 2000 GP SE 3.1 and have been having some odd problems lately. I recently got a code for the camshaft pos. sensor, and after repeatedly turning it off gave in and replaced it. that solved that problem however, I put some seafoam in the gas tank to clean my injectors,etc. about the same time and almost immediately got trouble code P0172 . I read the code (via Autozone's pos code reader) and it didn' tell me anything helpful. I have since been through two tanks of gas and it is still doing it. the next time it threw the code I went to Checker and used a better code reader. here are the readings:
Fuel system closed loop, P0172, system too rich bank 1, ltft bank 1 -21.0% stftbank 1 -2.3
intake manifold pressure 11.5 in Hg, RPM 1817, 61 mph, Throttle pos 8.2%, Mass air flow 001.89 lb/min it also had a little led flashing "EVA" which I guess would mean something in the evap. system is fouled up
everything else checked out fine including the o2 sensors, and I just barely cleaned the MAF sensor as well, spark plugs are pretty new, air filter is a K&N and is pretty clean as well
the code seems to regenerate only after driving about 80-100 miles
I have been getting a strange intermittent gas smell in the cabin, and the car is idling a bit rough and hesitates on acceleration, and on the freeway at steady speeds.is wrong with this car?? it's driving me crazy
thanks all, Jason
