1979 Porsche 928 Hesitation Problem
Hello all. I'm pretty new and finally picked up a 1979 5 Speed US 928. Timing belt/water pump was replaced as well as plugs,cap,rotor, fuel pump, fuel lines,cleaned fuel tank .. Problem is now while driving the car hesitates if you accelerate hard.. If you ease on it it drives regular.. Anyone know what possibly could be the problem? I checked for loose/broken vacuum lines already. thanks in advance for all who reply..
