Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I’ll be helping you today.
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 your patience is appreciated. JA is a great place, but it does NOT replace a 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.
Plugs, wires, coils and fuel injectors can all cause a misfire when under a load like that. Start with those components first.
