By the way its an 89 mkiii turbo supra. And let me go ahead and say it IS NOT DYING!!!! There is no struggle or what not. IT SHUTS OFF. I don't see a vacuum leak causing that, if a vacuum was leaking it would make it run like shit at all rpm's. AND believe me... IT RUNS GREAT!!!!
I'm down to it being an electrical connection of some sort, I don't know where it is at, and I don't know how to pinpoint it either. I know the second i put it in neutral FROM 4Th gear it shuts down, especially if i move the shifter side to side. But it starts right back up and i can put it back in fourth gear and it will never show any problems while in gear. It only shuts off after 4th gear to neutral. I don't think this is just a practical thing that can be known about because im sure that there are many things that could cause it. When i wiggle the shifter in neutral and it shuts down faster, that makes me think i'm making a connection or wire do something its not supposed to. I don't know if there is a ground wire on the shifter, or that goes down to the top of the transmission. And i don't have an obdI reader right now, so getting the code isn't going to be possible. And i don't even think it is throwing a code cause everything shuts down, nothing responds.
