Okay so this is what happened to my 02 camaro ss. This has happened 3 times now but this time it was the worst. Anyways, if the car has been running for a while or on a longer trip it will randomly start to sputter like it isnt running on all 8. When it happened this time my engine light started to flash. The other 2 times it happened i figured it was a loose plug wire and it seemed to work. Now my engine light came on solid and the code reads random misfire. What could cause this? Its weird to me that it only does it sometimes.

 

Random misfire is usually the result of a lean fuel mixture, although it could also be caused by ignition problems. It may be a good idea to check the fuel pressure with a gage, and change the fuel filter.

 

That is all good, it is getting way to much fuel also. I found that there are a few codes that it is throwing. The other ones are PO131 and PO151 which are the o2 sensors, so is it possible that one of my sensors is messed up which makes the car think it is running lean and therefore pumps way to much fuel into one side? Or is my thinking totally wrong ha.

 

The PCM is complaining that both upstream sensors are showing continuous low voltage. The PCM will then light the MIL and go into open loop. Once in open loop the PCM ignores most sensors and works off internal tables. I doubt that both sensors are bad, but could be a common electrical problem. The only common electrical connection I see is the fuse powering the heater circuits. If the O2 heaters have no power, the O2s won't get hot enough to work and show low voltage to the PCM.

Other possibilities:
Faulty O2 oxygen sensor
Short to ground or voltage on O2 signal circuit
High resistance or open on O2 signal circuit
