robertito - I will try that fuse thing this weekend, I haven't driven my car for about a week now, I have had no time to mess with it. I will let you know the outcome.

 

robertito:
I think your solution WORKS!!
I've a '99 GS300 and I'm having hesitation and sometimes jerk happen most when driving with low speed. I pull out the EFI (20A, where/what is #38???) last night, wait for 5 mins, put it back and go for a test drive. I found out shifting is more crisp and smooth during the low speed. I need more driving to tell the different but I think this is the way to go around it.

If you look in your Owner's Manual, there is a diagram for the large Engine Compartment fusebox. #38 is the one marked "38" ;-)
