Seafoam disaster

SO I added Seafoam yesterday to help clean up the carbon left over from a bad maf and running too rich. Yesterday, it seemed like the truck was doing fine w/ the Seafoam in the tank. Today I threw a Cylinder 6 misfire this morning and then after I got to work, the truck would not start. I troubleshooted with the excellent help of PT Schram for several hours and after I pressed the schrader valve near the fuel rail, it started. Then I replaced the plugs with Bosch Platinums. I was planning on running Champions but they were unable to be found here in Moab. Tonight I drove it at highway speeds for about twenty miles out to my night job, and it did fine with no misfires and running smoothly. On the way home I drove about 10 miles and then all of the sudden it felt as if I were running over large potholes when I accelerated. When decelerating, it did kind of a buck/bump but not as large as the ones experienced when accelerating. I let it gradually coast down to about 35 miles an hour and crawled home. The engine sounds fine, revs well, and does well with no bucking yet a rubber rubbbing against something (whatever it is I can not find) at in town speeds. Codes thrown are p0150, p1884 and the three amigos codes
Any Ideas?

Theres not alot in the way of plugs (at least on hand) available in moab. I figured since it is a Bosch engine the platinums would be ok. It showed these plugs as the ones for the truck on Napa's Computer.

Seafoam is just isopropyl alcohol and pale oil. I kind of doubt it would affect thing so much, actually I kind of doubt seafoam does anything in the gas tank as gas already has 10% ethanol in it (unless you added over a gallon). Sounds like you have a MAF problem maybe.

i dont think it has anything to do with a can of seafoam that you added to the tank. I run plat 4 plugs for 20k miles with no problems,.. what kind of wires are you running? are they 8mm?

Seafoam had nothing to do with it.

You're a moron for buying Bosch plugs...but if that's all they had, then fine. Replace them with NGK ASAP.

You're pretty vague with your problem. However, I say it's the fuel pump. Always is.

I'll get blasted for this but don't waste money on plats of any kind, champions or bosch.

At 50400 miles I replaced wires and plugs...used standard NGK plugs I'm at 122K and the plugs are still good.

ALWAYS? On a DII?

When the fuel pump was hot wired, the engine started and he was able to drive it home.

Power to/from the fusebox hasn't been confirmed.

I dont have time to look at your codes. I had similar intermentent symptoms. It was the plug wires. If it is your wires, be careful not to toast your CATS.

Ya he's got a thing for fuel pumps, would probably blame one for leaky sunroof. But I'm not going to disagree on this one.
