2001 q45 misfire
mechanic says bad coil but cannot locate which one. Is it possible to locate the bad one
or do I have to replace all coils?
The code would tell you that, I assume that is how he came to the conclusion that it is the coil, or you could do it the hard way and check the ohms on each coil and replace those that are out of specs.
