My '74 1.8 L-Jet 914 has developed a light load hesitation/stumble. It is the most pronounced when cruising on flat ground with light accelerator application, maybe 10% opening of the butterfly valve. The stumble is not noticeable when accelerating.
The car has: - New vacuum lines - New plugs, wires, cap, rotor, and coil (still running points) - Cleaned throttle body and checked operation of TPS - New accelerator pedal and throttle cable - Rebuilt MAF - Recent valve adjustment Does anyone have any suggestions for how to proceed with diagnosing the cause of my light load stumble (IMG:style_emoticons/default/confused24.gif) |
