Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

Misfires should set a code and turn on the check engine light. This will give us direction of what cylinder is being effected. Misfires are caused by either ignition, fuel or compression problems. Check your plugs, coils, wires, injectors and compression.

Thanks, Ron
