I recently purchased a 98 SVT, the car had not been running and the owner did not have a clue as to what or why. He did say that someone had replaced the "computer" and handed it to me in a plastic bag. I found that the PCM was incorrect and had an internal short. I replaced the bad PCM with the correct one (or so the dealership would have me belive)and got the car running but the codes 172/175 (banks 1 and 2 running rich) kept popping. Today was the first chance I had to drive the car. I cleared the codes and drove the car for most of the day. Took the scenic route as well as the freeway. and the car seem to run fine, just about the time I was ready to call it a day, bam code 172 (bank one running rich) popped. I cleared the code and drove it and it seem to hold. One thing I did notice is, I got a misfire while accelerating hard, at about 4800. "Whew" talk about the long why around the barn. So can anybody help me. What can I do to get rid of this code. I've waited a long time for an SVT I hope someone can help me.
Thanks
