A couple more questions on \'01 GTS (running rich) with more info...
Hey all,
I had posted a few days ago about some problems a buddy of mine is having with his '01 GTS in regards to a stripped spark-plug hole and running rich. He got the plug taken care of and we checked the check engine light codes with his OBDII scanner today. He had twelve stored codes for numerous misfires on Cyl 10 which had the stripped plug, a MAP voltage out of range, a couple high voltages on driver & pass O2 sensors (pre-cat) and two codes for bank 1 too rich and bank 2 too rich.
After clearing all the codes with the scan tool, he went for a quick drive and the only two codes that keep coming back are the:
P0172: Bank 1 too Rich
P0175: Bank 2 too Rich
We have checked ALL the harnesses, plug wires, sensors and anything else we can think of that might cause this problem, to no avail. Before this started happening though, he did get an Apexi AFS-II installed at a dyno shop who after installing the controller said they could not tune the car due to it running so rich. So the AFS-II is installed but just "zero'd out" not calibrated to the car.
At this point ANY amount of throttle input that would classify as more than what my grandmother would give it results in bucking, lurching, and overall cutting out of ANY power. This has actually caused some dangerous situations when pulling out into traffic. The car is idling between 760 RPM and 790 RPM, so that seems good. It's just when trying to get the car to move, or revving the engine while sitting still that the car seems to choke itself out.
Any help guys???
Thanks,
Nick
