truck surging idle and occasional stalling?

My truck just did the same thing and it was the ICP sensor.

Here also my 03' 6.0 would do the same thing loping idle. Jumping at the stop light then it started stalling. Finally threw a CEL. ICP sensor "low voltage". Under warrenty and dealer replaced sensor.

sorry i never got back in here but the truck was in the shop three times for this before they figured it out.

first time the replaced a glow plug harness. that worked for about a week.
second time they replaced a fouled glow plug. three day fix.
third time. they replace the entire engine harness. today is three weeks. the truck feels so much better. i waited two wekks before putting the tuner back on and man. im not sure if the truck was down on power all along but i gotta tell you the ****ing thing pulls so much better now with the tuner.

Glad to hear they finally got you fixed up! Took them about 4 times to get it resolved with mine. Changed out the engine harness and have not had the issue in 60,000 miles
