Trying to see if there is way to use HPT or something to check Injectors. I have a car I was trying to tune that went south just after loading a tune in it. Thought it may have been related to writing a HPT over Edit over Diablo, but ruled that one out, as well as the PCM itself, Coil Packs, MAF, TB, Wires and Plugs. I am down to checking rail pressure, which I am sure is good since all the plugs have more soot then a chimney sweeper. Thinking a injector or more is hanging open or just plain screwed. Any help is greatly appreciated.
