Dying Out

So i did some searching around an found a few threads similar to my symptoms, but as one fellow ORG member said i should just start my own thread, so here it goes:

Drove the truck about 200km the other day, got to my destination, an before i could even shut her off a friend needed a ride up the street, as i was sitting in the truck waiting for buddy to come out of the store, it almost seemed like my truck had a little extra knock to it, didnt think much of it cause we were ready to go.

When i went to pull onto the street thats when there was an obvious problem, sounded like she wasnt running on all cylinders, an when i looked back it was rolling some major coal. I quickly let off the throttle an set my TS chip to stock, thats when it started running real rough, so i pulled off the road right as it died...

My first thought was it ran out of fuel, because it was @ about a quarter tank, so i fueled it up, still no go, checked all conections, was getting fuel, used my Edge Evo to run the codes got 2, P1212, an P1211 that i usually get from my chip.

Called the tow truck an brought it to a repair shop, as the driver was lowering it off the tilt deck i tried it an she fired right up, still running like crap, so i turned the chip on, seemed to run better, turned it up to the next setting an it was running normal.

So the shop i took it to doesnt have the Ford Computer program needed, an the Ford Dealership in town is booked until the 25th. The boys at the shop i had it at figured it may be my IDM, or possibly the PCM failing. So i went an picked the truck up awhile ago an seemed to be running fine, didnt drive very far.

My question is, is it normal for the truck to run better with the chip on than stock when one of the Modules are failing?

Has anyone had any similar issues like mine?

Sorry for being so long winded, any help would be greatly appreciated thanks...

Henry...

Also about 3000km ago my alternator failed, after installing the new one my battery light has been coming on, an off periodically. When installing the new one i disconected both batteries.

Not sure if that has anything to do with it or not...

P1211{2}
ICP Pressure Is Above/Below Desired, Faulty IPR Valve

P1211{1}{3}
ICP Pressure Uncontrollable, Pressure Above/Below Desired

P1212{2}
ICP Higher That Expected KOEO

P1212{1}{3}
ICP Voltage Not At Expected Level


Sounds like a bad ICP to me, could be the IPR, too.

Test the ICP by unplugging it, then starting/driving the truck. If that clears it up, time to order a new ICP.

I should have mentioned, check the wiring going to the ICP and the IPR, and when you pull the ICP plug check to see if it's dry or oily.

I just went for a little tour with the ICP unplugged, the Engine light came on for the first time, got her up to operating temperature, an all was fine.

When I pulled back into the driveway, I turned my chip back on, an in the first two setting (75 - 100) the motor will kind of surge an Stumble, if I put it to the third setting (140) the motor runs smooth, same as with stock .

So I shut the truck off an plugged the ICP back in, an no more surging or anything so far.

So it seems to run a lot better with the ICP plugged in, also it threw a P1280 code when I unplugged it.
