Help please . With just the weight of your foot on gas pedal car surges then goes back to normal can do this most days then fine . Had so many things replaced to mention but only started doing it when I had the alternator bits done.
I'll go with that,
so the next step would be to check the alternator and battery voltages,
maximum 14.5 though usually around 13.5-14.00.
then the 5 volt supply to the five volt circuit.
as in it should be 5 volts not more.
