The spark plugs are numbered starting on the drivers side (1) to the passenger side (4), the distributor rotates clockwise, and the firing order is 1 - 3 - 4 - 2

On american cars the firing order is imprinted on the engine itself, if not the firing order is located in your owners manual it will also give u gap specs as well. Make sure the gap is right and firing order is right, If they are both correct then you might need look into your distributor or coil whichever ur case may be. If all this is correct, check and make sure ur wires aren't faulty and fouling out against metal or the brackets their mounted in. This is rare but it does happen sometimes.I hope i have helped you

Standing at front of truck, looking under the hood.
The closest cylinder to you on your right is #1. #2 is close left. #3 is middle right, #4 middle left. #5 is back right and #6 is back left.
Firing order is 1-6-5-4-3-2. This is the sequence for placing the wires on distributor cap in a clockwise direction. #1 spot on cap is the 3rd post after the wiring harness (clockwise). This post should be closest to cylinder #5.

Inspect for the correct routing of the spark plug wires. Improper routing may cause cross-firing. Inspect each wire for any signs of cranks or splits in the wire. Inspect each plug wire boot for tearing, piercing, arcing, carbon tracking or a corroded terminal.
If there is any corrosion, carbon tracking or arcing indicated on a plug wire boot or terminal, both the plug wire and component it was connected to should be replaced.
