I have a 99 SE V6 MTX with the TH fix and have noticed some poor driveability on cold starts. Yes, the throttle hang is fixed but on cold starts the car responds poorly to part-throttle tip in/tip out. It feels like there is significant lag between gas pedal position and powertrain response. These symptoms clear up when the car warms up.
Could this be related to a cold start ECU algorithm? Is some air bled by the TB through the bypass at cold start for some reason? Anyone else have this problem?
