today while driving out of a parking space i kinda gave the pedal a tap to rev my engine and i heard a POP come out of my car, i reved it again and heard the pop again, but then the third time all i heard was crackling, it seems like it came from the exaust could it be my cat?

 

Do yo have stock exhaust. Was it really cold outside. Was your car cold as well?

 

yea actually it was cold outside and my car wasnt cold, it was sitting for like 30 minutes before that. I was driving it and went into a restaurant to grab something to eat thats when i came back i heard the pop, I heard it last weekend too, while i reved my car a little bit you think its anything to do with the cats?

 

Hmmmm well when it is colder outside and you have the contrast in temp (exhaust gasses) you can have what some people would call a ' backfire' does it feel like the car is missing or is it just an audible thing. I had a very free flowing exhaust on my last grand prix and if it was really cold outside i would get a pop crackle type of noise only when the exhaust pipes had cooled. Once they would warm up it wasnt as noticeble if at all. You are probably hearing the same.

other than that do you have fresh plugs wires?
