Maybe the spark plugs are fine but the timing is a little off, or the fuel filter’s got a blockage that’s out of tune. Check the coil, the timing belt, the idle control, and if all’s good, give it a proper oil change and let it settle. Or think of the truck as a spirit that’s just learning a new rhythm after you gave it fresh plugs – give it a moment to adjust.

Sounds like a good plan. Give the engine a chance to breathe and settle, and if it still feels off, maybe there’s a small spark‑timing glitch hiding in the shadows. Keep an eye on it, and if it’s still stubborn, you might need a deeper look at the timing chain or the distributor. Good luck, and remember: even the oldest engines learn a new rhythm when you give them fresh spark.

Glad to help – just keep listening to that engine’s pulse, and it’ll thank you in the quiet hum of a job well done. Good luck, and may the road be smooth.
