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?

I meant I haven't changed the oil in my car 'myself' in over a year. I usually pay to have it done. My timing's good, it was serviced in March/April this year and hasn't changed. I tend to let the clutch out a bit slow (but smooth) because I have always been that way. It runs very very good, the only annoyance I notice is the very light hesitating right after shifting.

What about the fuel filter? Would that potential cause this?
