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
I suspect a weak fuel pump. It will probably get worse; have it checked before it leaves you stranded.
