Ford v10 p0352

Hello, I've searched this and other ford truck forums for the past week to try to find my solution, but ive had not luck.
I have a 2000 f350,v10 manual,4x4. I've had the truck for 2 years now. When I first bought the truck it had this p0352, p0302, and a MAF code. When I bought the truck it had new accel coils and boots. I traced the Maf down to a broken wire, which fixed it. Cleared all 3 codes and the truck ran well with no CEL.
About 2 months ago I was hauling a pretty good jag of wood and suddenly it started to misfire, got home pulled the codes,p0352 and p0302.
Swapped #2 coil with cylinders 6 and 7. Same code nothing changed checked the boots on all 3 they were good. Had very little play in the #2 coil connector so I replaced that, no changes.
Pulled the coil connector, grounded a test light and the coils getting signal, the light was pulsing. Put a new autolite plug in, no changes. Messed around with the harness to see if I could find a broken wire. Nothing.
I'm about to run a jumper from the coil wire about a foot from the firewall to see if that clears it up. I'd hate to mess with the harness like that though.

Any advice would be great thanks fellas.

On the V10s I would recommend Morotcraft spark plugs and Coils.

His choice of the brand of spark plugs or coils is irrelevant to the issue he's having. He's got either a wiring harness or PCM issue.

FWIW, the AutoLite plugs are fine, been running them for years in my V10 along with $15 COPs from RockAuto.

I'm leaning toward the pcm, I just can't believe that out of all those pins, there's 1 that's bad. Seems like a anomaly.

I'd suggest connecting your ohmmeter up between the PCM and the COP connector using the continuity beeper function and wiggling the harness. It's probably more likely a harness problem than a PCM failure, they just don't fail that often. Not saying its not possible, it's just rare while wire harness issues aren't as rare.

Well, I spliced a wire about 6inchs from the pcm and tied it to the coil, a pnk/LT blue wire and took a 5 mile drive and no codes or CEL. Before itd draw a code with in a minute or 2 of it idling. Must be a break some where in the harness. I think I'm going to just solder this jumper wire in and leave it. Also the pin was extremely loose so that could be it too. I'm going to try and repair that pin. Amazon has a kit for 16 bucks figured itd be worth a shot. Thanks for responding to this thread. Keep your fingers crossed that it's fixed
