02 Chevy Cavalier runs fine most of the time but occasionaly backfires especially when runing the AC. Talked to a gentleman at the filling station he said there was probobly a small hole in the diaphram in the low pressure regulator. Does anyone have more info on this problem or know a supplier for this part????? I changed thye plugs and wires a few weeks ago, It runs much better but still the occasional back fire
