Let me just say that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating.

They are sometimes bad about the ignition coils. There could be a bad one, (or more).

.

Recognize a non-functional or misfiring cylinder as follows:

  • Disconnect connectors from fuel injectors in sequence with engine running and observe engine operation.

.

Normally you could swap the coil for the missing cylinder to be sure before replacing it/them.

.

I can get the test instructions for them and put it in a PDF file, (it is rather large) and send it to your email address for as little as possible.
