I just had my distributor and Ignotion Module replaced along with the distributor cap. When I got the car back the mechanic said my timing was 15 deg retarded and he put it back to factory spec. He said the timing being that retarded would make it run poorly. But now that I am driving the car with the timing at spec it has a lot less torque and lags when I step on the gas (manual trans). Please help me out with this thanks.
