What causes hesitation in acceleration?
This creates a lean fuel mixture and conditions that are ripe for stumble and hesitation (also misfire). … Other problems that cause acceleration stumble include vacuum leaks, low fuel pressure, a weak spark caused by low coil voltage or bad coil(s), retarded ignition timing, and contaminated gas.
Do cars run better with full tank?
A lighter load does require less gasoline, but the weight of a full fuel tank is not significant. … per gallon), so even in most large vehicles the total weight of a full tank is under 250 lbs.
