I drive a 2001 Cobra Mustang each day. I've detected a slight intermittent miss. Then the check engine light came on but only for my drive home and not since.
I took my car to the dealer and they said #5 was dead. I asked and was told the plug, wire, coil and was functioning right. They tried new ones. They suspect a burnt valve or piston, or worse, but won't know unless they take off the head or remove and disassemble the engine.
Has anyone heard of a like issue? Do you think a leak down test would paint a clearer picture? Apparently that's a big job on this car.
At a minimum I seek a second opinion but am not aware of a shop that might be right for that other then another dealer. I live in the north burbs of Chicago
85K miles. Well cared for.
Merry Christmas to you all. (And please forgive my typo in the title for this)
