My buddy has a 95 V6 firebird and he has been having issues with it running really rough and backfiring on acceleration. I told him to look in to O2 sensors and replace the plug wires and plugs. He took into a couple of shop and they gave him various answers. One said timing chain and I was wondering if that is possible? Or could it be that his coil packs are crapping out on him?

Does a 95 have coil packs? Or is it an opti-spark? Or does opti only run on the LT1's and not on the V-6's.

Those cars are real tempermental about injecters. We had to clean the injecters in Stephs V6 at 78K miles. They can be real decieving when trying to diagnos

I had replaced plugs and wires along with two coil packs. Two cylinders where wet and two were dry so it made sense. Then I had my Buddy Sonic clean and flow test the injecters. We found two that were not to bad, two that were half way clogged and two the were not flowing anything at all!

They all cleaned up great. Stuffed them back in the car and it ran better then it ever did...until the fuel pump died

BTW after doing the injecters we got over 26 MPG in town and 34+ on the hiway

Tell him to floor it and run the crap outta it a few times, might help clean it up some...that's how I fix things, haven't blown a motor up yet...almost, but not quite

I tried that with my car but it didn't help, it only seemed to make it worse It felt like I was driving a new car after getting the injectors cleaned.

I remember that. Didn't you go through a couple sets of plugs in a week until you figured out it was the injectors. I wish I could hit that kind of MPG in the bird. It runs fine and I just did the plugs and wires but I'm lucky to see 20+ on the highway. Injectors were replaced with new when I did the engine swap so I'm pretty sure they're in good shape.

Mine was doing that too and it was the fuel filter.
