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?

Check to make sure the plugs are properly gapped.

When you reset your ECU, did you unhook the battery, let it sit for a few minutes, then hook it back up?

If not, try that. Then turn it on and let the car idle for about 5-10 minutes.

I've read in the tech manual before that sometimes when having work done that affects the ECU, it takes about a week for the ECU to relearn all the settings. I guess it's a fairly common customer complaint that their car doesn't run as well as it did when they brought it in.

I think you should check all your connections, hoses, etc and then give it a couple of days to see if throttle response comes back. If it doesn't, take it back to the place that did the work and have them inspect and drive it.

if the timing belt was off a tooth or 2 you'd really feel it, and it would feel sluggish and unresponsive.

^ True.

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.

thanks for your responses guys
i'll check that
from what i felt when driving, the timing belt is probably a tooth off
nevertheless, i will give it another few days to see if it's not an "ECU relearn" issue

just to confirm the prediction ... the tooth was off on the timing belt
response is fine now

...i just got a feeling that the new timing belt with other stuff is somewhat squeaking when braking with engine
it will definitely require proper check, maybe something was forgotten ... again

it looks like i have to start taking care of my car by myself, buying the neccessary tools will be probably cheaper than paying the prices in car repair service

The car is too easy to work on. With the right tools, you could do pretty much all the maintenance required, except of course jobs requiring a machine shop. Save your money for something else. I've never taken my Celica to a mechanic and never will. If I get stuck, I have friends with more patience and wrench-turning experience than me that can help.

Seconded

170hp? Is it stock?
We need engine pics

guys, i'm glad to hear that
the only problem is missing garage, but that's a problem only in winter
nevertheless, if i will be stuck at some point, there's always 6gc.net forum with plenty of knowledge to be discovered

rusty, be my guest:

it is standard 3S-GE engine without any modifications
in fact, my whole car is pure standard ... except the radio of course

nice
picture 5> 2v whats that bowl with white pipe going to the intake manifold? Is that 2 air boxes??

anyway what are you going to do to it

what pipe do you mean mate?
pls mark with red circle
it has only one airbox and one resonator as far as i know

well, there's some work to do in the interior like fixing the center console, it is squeaking; mount a radio properly including wiring the cable straight from the battery and switch for power antenna; check the left rear panel, it's making some noises too; repair the passenger's safety belt, the spring seems to be broken and the whole belt is just laying on the floor
afterwards, i will measure the engine power output, because it looks like i'm missing some horses
when all of this will be finished, the time for power increase will come
