This evening leaving work, after the truck had been running no more than 3 minutes, pulling away from a red light I gave it some gas, and nothing happened, than it took off fine, it did this once more than didn't happen again. I turned around and drove back to work, no codes, nothing else wrong it seems. It dove fine the rest of the night. Any ideas? Or just pretend it never happened?

 

What plugs you runnning, the Bosch 4's really kill idle, I had mine die a few times at stop lights...NGK's are in as of 5 hours ago, runs a LOT better. Could be some other mods, what you done to it?

 

it has stock plugs, the only mods are a FM cat back (I know, its crap) thats been in since Jan, so I doubt its causing a problem just now. thanks for the help

 

I am not sure but it sounds like some TM or Abuse mode kicking in to me for some reason. Not sure why it would only happen once or twice but maybe just the right combination of factors to make it happen. I would just watch it for a day or two to see if it repeats.

 

mine has done the same thing every now and then, and I've had my trans fluid changed 3 times and my tuck has 71k on it.

 

Had the same problem on my wifes 03 Trailblazer. Had it at the dealership for other reasons so I asked them to check it out. They re-flashed my PCM with some update and it went away. Now it's back, even after I changed the air & fuel filters. If you figure it out, please post the solution. Thanks
