How can I test my coil packs to see if any of them are truly bad?
My idle has been a little rough. Stalling when cold. Low & mid-range misses.
While I was in Austin, SVTADVISOR mentioned that I should look into a bad coil pack...
I was thinking fuel pressure, pumps, spark plugs, injectors, but coil packs seemed equally plausible.
Anyway, I got home this afternoon & swapped coil packs with a friend's Mach1 ... the ride actually improved.
So, I'm thinking some of my coil packs are bad.
Second question is, can I get them replaced under warranty?
How expensive are they?
