Swapping Coil packs, help.

[CreSTI]

I have a misfire in cylinder 4, P0304. Are all the coil packs interchangeable? Which side is cylinder 4? I want to swap the coils to see if the CEL follows it.

Coil packs are interchangeable. Cylinders go like this:

Tranny
3 4
1 2
Front

If your misfire doesn't follow the coilpack, check your plugs, and if they are ok, then you NEED to get a compression test. Also, with the engine running, pull off the oil fill cap and see if any puffs of smoke come out. If so, that's a sign of blowby, which can be caused by a cracked ringland.

Good luck.

Also you can switch injectors they'll cause a misfire

Yup, there is. Search my friend. Good luck. It's not a hard job. Also, get a Haynes or equivalent manual. Might pick up a FSM as well on ebay for $5.

Took me 30 seconds googling installing Sti injectors...
