What would cause my Crown Victoria to have a big boom to knock off the mufflers


Asked by May 03, 2015 at 12:27 PM about the 1986 Ford Crown Victoria

Question type: Maintenance & Repair

the car was having a problem staying running or it would just shut off when you stopped.
So we replaced the wires and spark plugs. Basically a tune up. And next thing I knew
there was a loud explosion sound. I am not sure what happened? Can anyone help?

Bad plug replacement, wrong gap to plugs, misfiring occurs when the firing order of plugs is wrong. Some years were recalled for fuel system problems and fires to the engine. Check ford recalls and appropriate manual for your car.
