have mechanic search for a GOVERNOR control switch. this device is an installed component that shuts down the engine at a specified cut-off limit, thus governing your speed check your catalytic converter. i had this problem and found out that every time i would step on it, a broken piece of it would blow up blocking the exhaust flow and when letting off the gas, would fall back down
My 1989 chevy s10 doesn't accelerate quckly,why is this?
i have a 97 Chevy Tahoe the amp. was above the gas accelerate mounted on a slant
the fuel filter has been changed.
Change the fuel filter
Could be a faulty spark plug or spark plug wire.
My guess would be wheel balance.
That's a Ford for ya...next time buy a Chevy
If the acceleration occurs when you are in a turn you probably have a broken motor mount.
check your drive chaft
you probably threw a rod out, get it to a mechanic ASAP or you will have more problems.
check cat converter if it has 75000 miles or more
have you checked to make shure that hte cruise control isn't on if your vehicle has one?
