Her's a good one for you Mike.....Exhaust backfire?

Post by canada karl »

Seems like it's always something. Went for a drive today....very hot ....over 32 Celcius. The car ran OK. but occasionally when I stepped on the gas there would be a hesitation before accelerating and a couple of times a pretty loud backfire. I didn't press too hard on the pedal but just went easy on it to get home.
