Diagnostic test info

[DawginDallas]

I know I have a bad coil - though I do not know which side (i have 2000 6cylnder).

Will the diagnostic tell me which side the bad coil is on?

Yes if you're throwing a code, get it read and it will tell you which one is bad.

it's a good 'guess' but not 100% accurate - so do not be surprised if it's not the one the car is telling you about.
