Slow throttle response Options

[kufor]

i'm new in here, so first of all "Hello everybody."

i just bought celica ST202 3S-GE (170hp) few weeks ago
on monday the first service visit has been completed:
change of timing belt, oil, oil filter, fuel filter, air filter and spark plugs also (NGK)
coolant has been checked and refilled, brake fluid too

unfortunately something got wrong, because the response to throttle is kind of slow comparing to what it was before the servicing
ECU reset didn't help

does anybody know what might be the issue please?
...or at least what to check before driving to toyota dealer?

you could also check to see how the Throttle Cord is possition. Unless you know the guys that worked on your car, some Techs either move stuff to make getting to something else easyer and forget to up it back, or they think they know where it should go or do and change it. Just a shot in the dark but stuff like that has happened to me and if your connection are fine then its something else to look at, i havnt looked to see if you can but i know on my friends old CRX and my old Probe you could change the possition of the Cord.
