Hesitation in 1994 C220.
A good friend of mine has a '94 C220 that has been acting up lately. It has a slight hesitation when you initially step on the gas. The idle almost seems to flutter like it is missing. The car has decent power after it gets over about 3000rpm. The plugs have been changed to try and remedy the problem but to no avail. Is there anything else I should check? The OVP has been replaced about 1 year ago to cure a stalling problem while driving.
