Help! engine trouble shooting

[jeff]

could this be why sometimes when id put it to the floor the truck would accelerate then all of a sudden like stop for a split second and go again?

Is this a major problem or a quick fix

so this just was coincidence with the tune? or maybe cause the tune operates the engine with a different idle/ gas use

The tune seems to cause the engine try to warm up quicker and get into a close loop mode faster to become more fuel efficient.. I not sure if they run a richer closed loop, and this is why people with tune and failing canister purge valve have the stalling and dying. Then once they remove the tune it gets better and eventually gets worse and happens without tunes.

Greg,
Thanks for the info, here I was thinking it may be the O2 sensor itself. Will try to replace it next weekend.
