Hey all, I just changed my plugs to champions. I started up the truck, and I noticed it's really..shaky, and I get the check engine light. I checked the gaps before and it's .040, just like what it's supposed to be. I have changed plugs before. I had the Bosch platinum +4 before, and apparently they suck. At that time...I had a check engine light and it still idled smoothly. All I had to do was rest the PCM, and it was fixed. Now I'm just confused with this situation. Any ideas?

 

What engine do you have? does each plug have its own coil its possible one of your coils are bad.

 

4.7L V8. And they all have their each individual coil. They all seem to be firing, tho. I might just buy a OBD Scanner off of Ebay.

 

I have a Snappon scanneri paid 3000$ for it. still have to get it up dated which is about a grand. but its worth every penny.

 

do the key thing what code do you get...sounds like a crossed wire to me...

 

it doesnt have wires its got coils for each cylender...

 

yea..to cross the wires on this engine, you'd have to be a complete dumbass. seriously...lol. the wiring sits right next to the coils. Well the ebay ones cost like..$30. All I need is the code..and it has the erase capability.

 

you can get a coil for 28.99 at autozone if you have one local.

 

my bad, what year is ur dak..you can have the truck tell you the code...if its new enough

 

2000.
