hi everyone i'm new here and i wondered if anyone else has had this problem. randomly my truck will throw this code (throttle position a/b voltage corelation) and reduced engne power.
the truck is an 05 4.8 ext cab mods are diablo programmer c.a.i and flowmaster. if i reset the code sometimes it comes back in like 2 min sometimes 2 days. also tried to remove daiblo tune same results.

there was a technical service bulletin for 03 and 04,they came out with a throttle body connector from dealer that corrects this.not sure if this is your problem since yours is 05 but maybe some info you can ask the dealer.the same code was being thrown out(2135).from the factory the engine heat was cracking the insulation on the TB harness and messin with the computer.
