Engine Mechanical problem
2005 Lincoln LS 6 cyl Two Wheel Drive Automatic 70,125 miles
Replaced coil on #1 & #4 plugs two months ago. Now, I have a backfire/ sometimes from take-off and a missfire sometimes at speeds of 50 to 60 AGAIN? Scanner at parts store is showing missfire/catalic converter problem. Dealer ship wants to replace four coils and Catalic converter. Service manager says the catalic converter is going out but also wants to do a tune-upand replace 4 coils? They will not replace the converter that is under warranty only? They want to do all kinds of replacements? Once i'm past 60 the car runs great?
have the same problem?
