Hey all been reading posts about ppl with hesitation problems,and I have a hesitation in first gear when I hard accelerate. Wondering if thats got to do with timing chains or something else.
Installed new plugs and have K&N CAI.
Ant thought would be great before I contact dealer should be warranty

I've only experienced hesitation in 2nd gear at around 2k rpm. It's torque management doing its stupid thing. Perhaps you have the same issue but at a different time. The dealer can reset the shift learning points but it didn't help me. Perhaps that's something you could look into.

Ok Jay thanx its just wierd it did it before the plugs and after its not too bad its just noticeable. Im going to clean the Throttle body and the MAF and maybe that will help .

Before I throw out a word of caution and advice don't we have Drive by Wire rather than the standard throttle cable?

Yes we do. What's your concern?

This tends to be a common problem with cars that are drive by wire, if you open the throttle plate without someone holding down the accelerator with the key to on it will cause the CEL to come on and the car to not react right when accelerating.

Correct. Someone should suppress the pedal with the key set to run as you spray the throttle body.

Hey Jay does yours do that? Punch the throttle and it basically burps for a second its noticeable and trying to figure out what I can before going to the dealer.

No, mine doesn't burp at WOT. Im still putting money on torque management. Each one of these V6s seems to have its own little differences.

Ya i can tell we all have our own little snags.

I say this all the time, no two cars are ever built the same. Each one has its own personality and it generally reflects the owner.
