Default Spark plug help!!

Hey guys, i kinda screwed up my truck more after changing the spark plugs. I was just wondering if maybe someone can take a picture of your spark plug wires and tell me what goes to where. I looked online i would just like to find out from someone who has a good running truck. If you are looking from the front of the truck, im talking about the 4 front spark wire plugs(The ones closest to you). Before i swapped the spark plugs and wires the truck didnt cut off while stopped. Now it cuts off, I think it has something to do with the fuel injectors, and fuel filter.. I just want to check this first.

If you do this it will greatly be appreciated. THANKS. and if it would be easier to chat over facebook or something let me know.


oh, and i have a 2.5, i forgot to include that!

Well, that coil pack closest to you (when standing at the front of the truck) is not the primary spark coil. the back one is. I thought there was a discussion on here about the coil packs on here...i'll see if i can find it.


here. check this post by TheStig. don't do the mod, just use the pics for reference...

and here is the sticky on 4-cyls. i think that top pic (lower section) has a diagram of the 2 coil packs (boxes with #s) next to the block sketch:
