This is the order to plug your leads onto the coils

rob drag racer thanks for the pic, i realized when i was installing the coils that the DFI module under neath the coils has the numbers printed on it, of which cylinder spark plug lead goes to what coil.

I ended up swapping the DFI module back to my original one and it runs a lot better with no backfire.
Unfortunately now it has a slight hesitation when i accelerate, any ideas.
