    jerking while on throttle

    Just bought a 86' 316 E30.. when I bought the car it took a very long time to start (a few tries) and I had to give it some gas for it to start. For the week that I've owned it, my friend and I have already replaced the in-tank fuel pump, fuel pressure regulator, spark plugs, new wires, cap and rotor looks new. It runs a lot better but its had a jerking issue since the day I got it. It occurs when I get on the throttle on either 2nd or 3rd gear, the car hesitates. My friend told me my cat could be clogged also.. any other ideas? Any input appreciated! thank you

        I have the same issue. I replaced the rail fule pump but not the in tank pump. Im also pretty sure that my cat is shot. Thats the next thing to try. let me know if you find the problem and I will do the same

              That would be "fapping while on throttle"
