P0304

Hi Guys,
On my way to work this morning, the car started running crappy and the SES, check engine light came on. I luckily had my code reader in my glove box. I pulled a PO304, cylinder 4 misfire. I suspect its the coil pack. I just went to the boneyard this weekend and pulled 6 coil packs and they are in my trunk. Oh, what luck! I do not have any of my diagrams with me, so I need to know which cylinder is #4. I will look online also. Thanks a bunch.
Phil

cylinder 4 is in front of the radiator, the middle one.

Cylinders are numbered as follows:

In the back by the firewall, from the passenger side - 1 3 5
In the front by the radiator, from the passenger side - 2 4 6

This next weekend is 40% off at the wrecking yard. I think I will go and snag more spare coil packs. This is the second coil pack failure in 3 months, so some of the others might be on the way out. BTW, Shrout1, I put a copy of your diagram in my code reader book for reference. Thank you.
