A spark plug wire broke, so I replaced all of the wires and the engine still misfires, why?
My 1993 Dodge Dakota V6 was running just fine until I decided to check the condition of the spark plugs. I pulled the wire out by the boot (as recommended) and the thing still broke! So I went to the auto parts store and bought a costly new set of wires and put them all in properly, making sure they clicked in.
When I start the truck and put it in reverse, it bumps up and down. The engine is certainly misfiring, but why? I replaced all the wires!
Only two things I can think of: 1.) Perhaps I put the wires back on not in correct order and now they’re improperly crossed, or 2.) I damaged something while replacing the wires.
What should I do? If I take this to a mechanic who knows what I’ll be charged. Is there maybe a diagram showing the correct wiring order of the spark plugs?
Thanks!
Yes! It was indeed incorrect firing order. Went to AutoZone’s website, printed out the diagram, 1-2-3!
Thanks a lot guys I appreciate it, because of you I have my truck back again!
check your firing order there should be a label under your hood at the front that has information about your truck. It will list the firing order the type of spark plug to use and the gap to set it at. If you changed all the wires I would also change the plugs at the same time. Get some Autolite plugs great plugs and don’t cost too much. stay away from Bosch there stuff sucks.
Its possible that a plug was damaged when the wires were replaced.
