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 patience is appreciated.

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.

Sounds like you have too much resistance in those injectors, check resistance on ALL of them first cold, then hot.

Thanks, Ron
