Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started!

So you either have a injector issue or timing problem, I would think it could the vvt solenoid

I unplugged each injector one at a time and each time it ran worse when disconnected and better when plugged back in

What and where is the vVt sensor and can I do an resistance check to verify it’s condition?
