Re: Need help! Engine hesitating
i've had a similiar problem for a few years now but mine only sputters when cold, once at 150 degreees and up, its fine. i changed the wires, plugs, cap, rotor, fuel filter as you did with no results. i'm interested in the replies you get from others.
could also be your ACT and/or ETC.
what is the voltage on your TPS sensor?
FYI i dont like the splitfire plugs. i think most people here would agree that autolites or motorcrafts are your best bet. cheap copper.
