Hi Wayne. Go to any auto parts store and get a bottle of a fuel tank additive called seafoam. This will clean your injectors, and all of the internal engine parts. Drive for ten miles or so and u should be running smoothly again. J.

Why would engine run rough after tunr up?


Are plug wires connected in the right firing order to the plugs? Also are the spark plugs gap correct? Was vehicle running rough before tune up or only after?

Starting and rough running


Have a complete tune-up done and re-post with specific symptoms if it still is running rough.
Most likely you have either a vacuum leak or bad ignition part (spark plug or wire... possibly cap or rotor, too).
In extreme cases of neglect the fuel filter can be so fouled it will not run properly.

Runs rough and wants to stall on acceleration also runs rough when ac is turned on


It sounds like you need a complete tune up and filter change on the car/truck. By doing this it should correct your problem. Hope this will help you.
