So, on Friday, my truck starts running rough. Idling vibrates the whole truck. I noticed driving home that I was getting a lot of detonation above about 1500 RPM. So, I limp home and go get some Lucas Octane Booster in my wife's car. That cleared the detonation up, but it's still vibrating at idle and running rough as hell. The weird thing to me is that it's not throwing any codes. What do I do here? How do I get her running right again? Please, any and all advice is needed. I need to get things moving back along today, because I have to drive back and forth to work all week.
