It seems like randomly the car will backfire alot. Sometimes the car will run perfect and stront then once the car cools down completely and i go start it up again it will run like ****. Seems like its misfiring. Once it cools down and i run it again it runs perfect again. The car has a cam, and minor boltons... Its a 2002 Camaro with 55,000 miles.... The plugs were changed at around 30k. but not the wires... Does anyone have a clue why the car dows this randomly.

 

do you have a flashing SES light?? if you do that could be foul spark plugs or bad wires, but it could also be a sensor is going bad or something minor like that, what plugs do you have in there right now and what is the gap???

 

I would say the plugs and/or wires. Mine did the same thing, changed plugs and wires, now it runs like a dream.

 

my tuner changed them with non platinum plugs, he said they are better... No the SES isnt on, when the car was tuned he took out alot of things like egr air and others.... The car has a 228/228 .571/.571 112 cam in it.

 

Check if the wire are on tight and also if you have a loose plug.
