Fuel Response Options

[6G96GT]

I had a diagnostic and full service inspection on my Celica done from a local Toyota Dealer. It passed with flying colors so I know there's no large concerns at hand that would cause my car to have a fuel issue. Anyway, here's my issue:


Whenever I am driving around (city driving that is), right after I shift and then press the accelerator pedal, my car lightly hesitates, it's not a smooth transaction kinda deal. It started happening about 3 or 4 months ago but now it seems routine. Doesn't matter what gear I shift into either. It's a very light (but noticeable) hesitation (under normal driving). If I were to accelerate it hard, there's no issue at all. Only when normally driving and shifting. By the way, I shift gears when I reach 2.5K - 3K RPM under normal driving.

I really don't want to pay a mechanic to spend hours troubleshooting if I can help it. What would cause this issue?

Well, I checked the throttle body, looks good. I forgot that I had it cleaned and serviced when I had the head rebuild. Spark plugs are good too. Could it be my clutch getting worn out? I haven't replaced it since I've owned it.

By the way, I haven't performed an oil change on my celica in over a year and can't remember if I am supposed to put oil in the new filter and then screw it on or don't put oil in it???
