2004 GMC Sierra 1500 Question: how do i fix a cylinder 4 misfire or what would be the cost to get it repaired?
It's hard to give an estimate to fix a problem without having done some basic tests and figuring out the extent of the problem. A misfire can be caused by a bad fuel injector, a vacuum leak, an ignition problem or an engine mechanical problem. - patrick mannion
