My buddy called me up last week and said his car was running llike crap. He came over and we hooked up Atap to take a look. Without posting the list, a whole bunch of codes for switching, high reading, out of range, etc..., for both front rear, bank 1 and 2 were all shown. We cleared them out, and the car ran fine for a couple days. He called me today and said it is running bad again and the light is back on.

The car is a mostly stock 98 SS with a lid and ORY. It has simms for the rear O2's, but they still coded somehow.

Any ideas? Wiring, PCM maybe?

check the engine sensor fuse ... if it's blown check your O2 wires to make sure they're not hitting the exhaust...

 

Did you get it fixed? I am having a similar problem, where is the engine sensor fuse?

 

I think it was just bad O2's. I had one spare O2,so we didn't change them both. I will try to get him to post here. He posted somewhere else that now the O2 I gave him stopped coding and the other one still is. It just seems odd they would go out at the same time, that's all.

in the engine bay, one of the boxes on the driver side... I believe the box closest to the front... it's labeled as Eng Sens I believe
