Re: Pulsing engine?



Gary,
A lean mixture will cause this condition. No one mentions the fact that today's premium fuel is the octane equivalent of regular grade back when our cars were designed. I have to think we should use the good stuff for best performance or detune to accommodate the lower octane grades.

Hi all,

Any thoughts on what to check? Poly 318 2bbl runs fine at idle and real smooth when accelerating.
But driving at a constant speed (any) there is a slight pulse/skip/hesitation.

Thanks,
Gary H.
