Having problems with your 1990 Ford F150 ?
Truck runs rough
\015 I have a 1990 Ford F150 4x4 300 6 cylinder. The truck seems to run fine when you first start it in the morning and the engine is still cold. Once it warms up the motor starts surging and idling rough and bucks and kicks at a steady speed. And has a strong fuel odor coming from the exhaust.\015
Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.
