lunging again

[GS247]

Ok my truck is starting to lunge again. I replaced the IPC sensor like everyone recommended, and it seemed to help for a while. Now my truck is acting up again. Its like someone just instantaneously just stabbed the accelerator pedal. Sometimes it only does it for a second and stops and other times it will hold it for 5-10 seconds. Its like something if fueling the engine. Yesterday it did it and then as the RPMs were coming down they just kept dropping and the engine died.

Any other suggestions?

Would a TPS do this and are they common?

I have no hard codes. I am going to have a buddy hook up his scanner and pull the codes.

my truck is in my sig.

bump...

any ideas

hmmm thats a hard one. either a TPS or i dont know if i could be but would a CPS going crazy cause it??

whats a CPS

Does it still act up if you take the tune off?

[GS247]

yes i have changed it from my xtreme tune to the canned tune, to stock and it does it with and without the tunes.

cps is the cam position sensor

would the cam sensor cause this problem? ive heard of it causing the engine to die or no start from the cam or crank sensor.

I still have this problem and no one can figure out what is causing this. I took it to the shop and had the comp scanned and the only thing he found is a P0603 (soft code) Internal control module KAM error. I did a little searching on here and it looks like my programmer caused this.

I’m just frustrated and cannot figure this out. i wish it would through a CEL to give me some direction.
