my car runs like ****, keeps bogging down and dieing. I had a local performance shop check my codes and cylinder #3 misfired 2x. All 4 o2's read bad. I have already changed my spark plug and wire,and 1 check valve, after firing it back up it's still doing the same thing. Ne ed help!!!!

well your sig shows that you have an ORY, you may not even have rear o2 sensors, so thats one thing down. The front ones may be bad, if so I'm pretty sure that will make the engine run crappy. Replacing the wire and plug should have gotten rid of the miss fire. What condition was the plug in? That can give you a pretty good idea of whats happening in the cylinder and maybe prevent it from happening again.

can the blaster pack coil go bad? the spark plug looked a little burnt so i went ahead a replaced it. i have 2 o2's in my y pipe. I ran the car a few minutes ago around the neighbor hood. It just wonts to die, and when i got back in the garage i could smell somthing was burning, or getting hot.

did it smell like gas or no?

It it smells like its running rich, you could have 2 front 02's bad and its causing a rich condition.

my exhaust smells like gas, but inside my motor on the driver side it smell like somthing is burning, but i cant really explain that smell.

Fix the front O2s first, then look at the #3 wire, is it sitting on the header and burning thru the insulation (that could explain both the missfire and the burning smell, also check around the headers for wires that are close, especially the O2 sensor wire(s)that could be the cause of the O2s going bad and the burning smell

(if your front 02s are shot)go to summit and buy the front o2s for 120 i think...their better replacements ..i think theirs ngk or ntk i forgot.....
