Let me preface this by saying yes, I am pretty slow, but a couple months ago my 1989 740 gl developed a heavy misfire on cylinders 3 & 4. That morning I accidentally revved it to just under red line and it seemed fine until I was driving to work and it started stumbling and eventually died. I pushed it into a parking lot, finished my shift and then got it towed home. It then proceeded to sit for a couple months until I could get my uncle to help me look at it. It has good compression, good (I think) spark, and all the injectors are working with decent fuel pressure . We switched out injectors, engine temp sensor, fuel pressure regulator, intake gasket, and throttle body gasket and the problem still persists. Im at a loss as Im not much of a mechanic (yet) and my uncle typically works on diesels. Any advice would help thank you.
