It is a software issue. What year is your car? what month was it built?Weedo said:When I take off, say, at 1/4 or 1/2 throttle, and the car goes from 1st to 2nd... once it hits second it feels normal, then for a second or two it seems to drop down lower in the rpm band, almost like the torque converter is locking up. What is this? Why is it setup this way? Is anyone else experiencing this? I thought I read about it somewhere but couldn't find it when searching.
There is a TSB about hesitation under moderate throttle. It happens occasionally with my car, despite software upgrades. If I pull fuse 11 - leave it out for a few minutes then put it back in - it forces the main computer to reset and the problem goes away for a few weeks.
