The engine light came on, took it to advance auto, dont know the code but he said the o2 sensor, cylinder misfire, fuel injector, cylinder misfire.
i replaced the spark plugs and wires, coil packs, the rear o2 senor, poured in sea foam into the fuel injector. nothing, still the same
can somebody help me out, the engine is running roughly, shakes and barley goes when hit the gas pedal

 

Replace the Rotor and Cap yet

yes / no

Yes, issue sounds like a spark strength. maybe time for distrubitor change

No, replace the cap and rotor. retest. report back

 

we think its was some bad gas, none of this was happing before i put the new gas in it
