Still having low power on my m70, so far I've done the while ignition system, fuel pump, fuel filters, gaskets on the top end, rebuilt and calibrated throttle bodies, and cleaned the injectors. What could be the cause? I get an occasional misfire at idle and an occasional o2 sensor code.
Ran like a train when I bought it but it was getting 6mpg so I figured it needed a pretty good tune up. I'm 90% there's no more vacuum leaks too.
--another problem, I now have to manually jump the fuel pump relay.
