3964larry Posted May 15, 2008 Report Share Posted May 15, 2008 Took 96 eldorado 4.6 to mechanic i've known for years to install blower motor. After installation ,the car missed real bad.With 95000 mi. he suggested plugs and wires.Still missing and vibration at idle andup to 30 mph,then sounds ok.Engine light is on ,so he keeps car two more days. He goes over it and checks vacum hoses ,coil pack,checks for loose connections--Nothing. I let him off the hook.brought it home .the only code showing is pc0300 which means it is missfiring. I am stuck. can you please give me some ideas? Thanks Link to comment Share on other sites More sharing options...
