Question Asked: My car is missfiring and backfiring
January 18, 2014, 04:47 PM
I have a 1990 cadillac seville. It has been missfiring on me and it backfires and looses power sometimes. The service engine light comes on and goes off. I changed the distributor cap rotor button and plugs and it still does it. I turn the car off and start it again and it runs better. The other day it backfired and was losing power i cut it off and started it again and it backfired real loud and it blew my muffler apart at the seams. I changed the muffler and its still missfires and the light still comes on and goes off. When i barely hit the gas and go under 40 is when its missing and jerking when i step on the gas and it opens up it doesnt jerk. Does anyone know what it could be
