Jerking with a cloud of white smoke

Man, it's getting real weird. Maybe something in that area is putting out some high interference. JK

I hope that does fix it.
Did you say the Napa ICP was new?

Yes the Napa is new.

Basically truck had very bad intermittent smoke/stutter problem. ICP had oil on it (quite sure it was bad), replaced it with Napa. Still have problem, find ICP connector is bad (misses if connector is moved) replaced connector now it only has problem in this spot. There is a cell tower on this hill and I am told there is a bunch of radio gear on that tower. It is quite odd. I think there is an amplifier circuit in the pressure sensor and the Napa circuit is not as stable as I might like. Quite frustrating, hopefully this fixes it.

I am very aggravated with Ford that the PCM does not see a problem with the ICP dropping to 0 suddenly. Why doesn't that throw a code? Any why can you have the sensor unplugged without a code?

Well it's the first gen programming.
I think you can have it updated though.

I just e-mailed DP Tuner to see if there was an update that would effect this.

Thanks!

New Ford sensor is in and no problems either direction at that spot. That is conclusive for me. Now to change the uppipes.

Napa said they will take theirs back, good thing, it was $177.
