jesseebaker Posted October 4, 2009 Report Share Posted October 4, 2009 my 91 sedan deville is missing at low and high rpms. my mpg's have dropped considerably. I'm going to start with the plugs and wires but was wandering if anyone on here new an easy way to get to the back plugs. I'm just a shadetree mechanic trying to save on another bill, and the back plugs seem nearly impossible to reach. i thought about loosening my motor mounts and jacking the motor up, but the exhaust won't let me do that. Any suggestions, or should I just bite the bullet and take it to the shop? Quote Link to comment Share on other sites More sharing options...
