my o2 sensor probly needs replacing, and my fuel filter i just replaced when i did my plugs last, but how do i check for a leaky injector? by the way its not like a bang when i hear the back fire its sounds more like a mufled poping almost like its a pop corn maker and sounds like its in the cat.

I had a leaky injector once and it blew a fist size hole in my muffler.big shot gun boom and you saw every body ducking for cover in the block.hehe. also the leaky injector left the spark plug oh so black so check em but I don't think yours are leaking with just a pop.

Hey i just found this forum the other day because of the same problem. i was told to clean up the egr bpt tube, but didn't help. then i played with the timing. i retarded it a bit and it took most of it out. i also have done a complete tune up last week.
