Make sure you're not in snow mode -- that is 2nd gear start I believe.

Just got the car back from the 50K service. Problem solved, but I have no idea what the solution was. Either way, I have seamless, strong acceleration. Its like they reset something at the service department. Even appears to have more low-end torque

I'm curious to know what they did. I won't accept the "placebo effect", just yet

Hmm. still thinking. I did have them balance the tires (50,700 miles), but I doubt that would have a obvious affect. Incidentally, I don't recall other brands charging for balancing wheels when they rotate them though. I figured it wouldn't hurt. On a side note- how often do you all balance your tires?

Datacom9,
For the sluggish feeling you’re describing I would suggest resetting your ECU. Just pull the negative battery cable and let the car sit or 30 min, or just pull the ECU fuse in the fuse box. When I bought my SC it felt sooo slow, it was previously driven by a 65 year old lady. After resetting the ECU the car came to life.. I was able to light up the tires from a stop with no problem

Know what? I think you are on the money. I had them adjust the sensitivity of the headlights, and they may have reset the ECU in the process (I noticed that all my radio pre-sets were lost, so they may have unplugged the battery for whatever reason).

Anyway, I've found a number of very minor things that were overlooked in the so-called CPO certification process. I doubt that they reset the ECU as standard protocol.

It has been a few days since the service, and there is a definite, non-imagined change in the shifting/torque. The transmission shifts like butter and is much more responsive with absolutely no hesitation. I haven't had the guts (or the need) to go wide open throttle since getting the car back

Which is the ECU fuse? I would like to reset my ECU, but don't want to lose all my phone book and radio presets (call me lazy)...

I think it could be any/all of fuses 72, 73, 74, 75, 83, and/or 85? Can anyone help me out with this?

According to this page, the fuses to remove are 83 and 85, the ETCS and the EFI (10 and 25 amps).

Anyone have any experience with this?

Default Low Torque

I was glad to see that someone else mentioned the resetting of the ECU. As I was reading through the post, I knew that is what the problem was. I have done that on every Toyota/Lexus I have owned (7) and always notice a difference. the part to add, is that once you have reset the ECU, I have always been told that the car is learning your driving style and to therefore go out and put your foot in it for about 30 minutes. I do not know that it takes that long for it to learn, but thta is what i have been told. Maybe it is not needed, but I tend to reset the ECU every year just to be safe. it also works to clear a code to get rid of a pesky "Check Engine" light if you have had an issue.

I wil do this, too. I was percepting this... "drag" effect, too, like the e-brake was on. I even pulled the e-brake release and tried lifting up on the pedal thinking it was stuck or something. I just really noticed it this weekend. Will report back with my findings.
