Need help diagnosing CEL
Well after I out Tommy's tranmission in the car, I got a CEL, and the car runs like crap.
The CEL will go off with the ignition key cycle, after around 5 minutes of run time the CEL comes on (closed loop?) The car runs real rough, feels like it's loading up, until I give it enough gas to get past 3K RPM, then it takes off. Feels kinda like a carb car when running really cold. After it warms up fully, the CEL may turn off, after a while come back on, and may repeat this cycle 10 times or more on my drive to work. I ran a KOEO test, and tried to read the CEL flashes, but it seemed that they all were 2 or 1 digit codes. From what I have read, 94/95 should always be 3 digit codes. Also I may just be reading them wrong. I was thinking maybe when I had the O2's out (when doing the transmission) that one got damaged and is now not working correctly. I just want to make sure that I replace the correct part when I fix it. Any one have a code reader for a 94/95? Anyone have a code list for 94/95?

Never mind, I answered my own question today.
I need a left hand O2 sensor, of course I will replace both at the same time.

really surprises me that an 02 sensor problem would make that much of a difference in the running of a car. Sure gas mileage would suffer a bit, but I wouldn't have thought it would cause it to load up

Craig, I have a code reader if you need to borrow it anytime.

Well I changed out the LH side O2 (auto zone only had one in stock length) and the car runs great, so far.
I was only able to take it for a short test drive.
