What would case my 99 gmc jimmy to bog down and run rough when giving it gas


If you have replaced the fuel filter this year, the next thing to check is fuel pressure with a gauge. GM vortec engines require 60psi or more to run.
If the check engine light is on you should also have the computer scanned for trouble codes.

Starter kick back


If this is a gas engine, check the ignition coil or plug wires. A simple test...

Start the truck at night, then look under the hood while it's running. Don't use a flashlight or your headlights; it should be dark !

If you see sparks anywhere around the engine, you've found the problem. Now you can turn on a light to see where they're coming from - probably from a cracked ignition coil.

Good luck !

1994 Buick Century - high idle, hesitation @ speed & little power


Have u checked to make sure that the fuel filter isn't plugged, and it could be possible that the fuel pump is bad -being cracked or haveing a bad seal in it allowing fuel to leak back in the gas tank, as soon as your fuel pump warms up the leak would expand dropping your power
