    Question 06 Impala LTZ Hesitation problem

    I have a 06 Impala LTZ with the 3.9 engine.
    The car has approx. 12,000 k's(8400 Miles).
    Here the thing, it doent do it all the time but when you are on a merge or at a lower speed you step on the accelerator and nothing happens for a couple of seconds.... and then it takes off. any ideas?
    Other than this its been running great.

    Does it have "Drive by Wire"? Otherwords a Electronic Throttle? Meaning no actual throttle cable...controled by a computer chip.

    It could be learning your driving style. My 07 Camry has this....annoying at first. Now it is smoothing out...

    I had the same thought, if you have never driven a car with wireless throttle, get used to it. If there is no Service Engine light all is well in car land.

    All 3.9L equipped vehicles have electronic throttle control. Some hesitation is just a normal trait of drive-by-wire throttles. I haven't noticed this in my G6 GTP, but I could just be use to it.

    I've got no hesitation with my 5.3L SS...and no it's not the huge amount of torque making up for it

    Could it be a combo of both electronic throttle lag and also the lag while the tranny is doing a 2 gear downshift?

    Try manually putting the gear shift selector into a lower gear and punching the throttle. If you get more response then it's because you're waiting for the tranny to shift...if you still have lag then it's probably the throttle lag.

    I should have thought of that...that site is a good place to play around with on occasion to see what new programs are available for your vehicle. I've found a few issues that i was having that i found to be covered by a few of those bulletins.

    I have dealt w/ the hesitation issue as well w/ drive-by-wire throttle. 05 Maxima...mash the throttle on on-ramp...takes a sec or so before any reaction...they you're off. I love the instant response of the newer vechicles (early 2000s) w/ actual throttle cables...at least GMs cars.
