Help! -- Misfire Under Load
I have a misfire on my '97 4.6L F150. I took it to auto zone and found code P0304 (misfire on cylinder 4).
1) Is cylinder 4 the back one on the driver's side or the passenger's side? Auto zone said it was on the driver's side (that plug and wire looked fine / no moisture), but I thought number 4 was on the passenger side.
2) What should I be looking for in troubleshooting the problem? I changed the plugs and wires at around 105,000 miles and have 112,500 now. Should I be looking for moisture? The coil pack? Or should I just take it in to a service center?
Thanks for any and all help!

#4 cyl is on the pass rear, check the hose on top of that plug it they are notorious for leaking coolant on top of the plug and shorting it out.
and here is another tip stop going to autozone the parts are junk, I just replaced 2 one month old cop's from there and bought motorcraft instead.

The wires did come from Advance...I think I should have got the motorcraft.
