As the title states, some a**hole screwed with my spark plus while I was at school and now my truck is backfiring like a 87 toyota corolla.

Does anyone know where i can find a diagram to replug my wires ?

Thanks

 

its either on the core support sticker or the under hood sticker...the diagrams were there from the factory

 

What engine?

 

I'm guessing by his sig...his truck...its a 302-5.0L

 

good call bowtie. Thanks

Firing order 18736245 I think starting at 1 the rest goes clockwise.
cyl layout

left side facing engine 1234

#1 plug front left of engine front to back

 

Thanks guys, I replugged them in the correct order and we're now back in action.
