Firing Order
Hello All! I went through the forum and couldn't find an exact match to my problem so I decided to start a new thread.
Firing order.
I have a mifire on cylinder 5 (autozone diagnosis) and I'm guessing it's the coilpack/wire/plug. Is the firing order on these modular motors (I have a 4.6L '98 f150) the same as the old windsors and clevelands? (1-4 pass, 5-8 driver side) It's a pain in the *** to drive right now...I don't wanna hurt the thing and it sucks looking at a check engine light. Any help would be great!

btw, just had a look. my truck has 2 coil packs, not coil on plugs. i jerked around with the wires pushing them hard into the packs and it seemed to help just a bit. i'm guessing i'll need new coil packs. any suggestions?

How old are your plug wires. If there old may need to replace them if there in good condition try some dielectric grease on the spark plug wires the moisture gets in around the sparkplugs and causes it to miss

Make sure there is sufficient dielectric on the spark plug boots. Thats where the moisture gets trapped. I had new wires too with the same problem. That was the problem with mine. only happend when it was wet though. Probally not easy to check with all that powersteering reservoir and brackets in the way

the order is still the same #1 in front #4 in the back . did you check for a coolent over top of the #4 plug it will short out a new plug wire. it is a short rubber hose and the clamp will get lose .and make it miss all over again .the coolent will get between the wire and the boot and short it out.
