My golf car has been raising (high) on its own (i mean the engine) even when I am not pressing the accelerator what could be the problem? I have called the mechanic to check on it, he bought a cadburettor cleaner and did some work on the caburretor, yet it does high some time on its own.
Secondly when I start the engine, the engine cranks and roll very well but it takes some time to start some time I use to press the accelerator before it starts, the mechanic said it is the plugs, what do you think?
