Mercury Marquis Compression Problem
Upon hard acceleration ramping on to the interstate, engine has a intermittent hard miss. It has new platnums,wires, cap &rotor.
Smooth idle at start up but occasional light miss when warm at idle.
Any help out there?

Tom:
CHeck to make sure the fuel pressure is within spec and check engine compression. You may have a cylinder that is low on compression.
