hesitation and surging 0603 code tripped
I have a stock (other than a 1705 supertuner) 99 late 7.3. My engine is tripping a 0603 KAM error code read on my superchips 1705 tuner. the engine is extremely sensitive to throttle position off Idle and when coasting downhill on the highway with the converter still locked up. Its like a TPS position error or something. its only in the first 1/2 inch of throttle travel, ...it doesnt do it all the time, hot cold doesnt matter.
It does it with the stock program in it and also with either of the superchip tunes installed (toew or performance)...The dealer says I have a chip in it even though its in his hands with the stock program in it.. he hooked up the IDS and CND it.
