Folks, I have a 1990 760T wagon that is running like crap, and I just can't seem to find the cause. Basically, it's choking and dying and gasping and dropping cylinders. Sometimes at idle, always when driving and under load , especially when I punch it, not so much when I just very gently and slowly accelerate, not so much when cold, much worse when hot. I have replaced the plugs, wires, cap and rotor, all vacuum lines, air intake hose from AMM to turbo, checked all other air fittings, and here's the confusing part.... the computer tells me all is well, life is good, no errors, all clear, 1-1-1. WTF am I missing ??? Any help and insight would be most appreciated, thanks !
