Nope, the check engine light never came on. Their explanation for this was that the computer only allows a problem to trigger the check engine light after multiple malfunctions. For some reason the sensor wasn't faulting enough to register although the performance issues were obvious. After enough complaining, including calling the owner of the dealership directly, they agreed to supply an identical 2001 GS300 from their pre-owned lot for back to back driving comparisons - this was the only way we were able to convince the service rep that there was a problem!!!!

:) Problem Fixed! After following the advice of whoever posted resetting the ECU, the dealership has redeemed themselves. They first told me the ECU couldn't be reset - then they magically found out how to do it. On top of that, they took the car for some real-time diagnostic checks which turned up a faulty oxygen sensor that wasn't registering a problem with the computer. The combination of problems has been solved and the car now scoots as it should!!!! Thanks for everyone's help.

I have a 2001 GS300 that has some major issues with accelerating. Any time you floor the vehicle it hesitates for what seems like forever before accelerating. It's a major problem driving around, I've almost been rear ended a number of times pulling out in front of traffic, only to have to wait for the tranny to find the right gear. It's been to the dealer two times already for this issue, which they say is completely normal for this model!! Help!! Is anyone else having this problem?
