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?

Really? I've always shifted at that range. What is the optimal range stock??

Also, what about when you're cruising on some back road? When I'm in 4th at say about 40 mph, my rpm range is about 2K. What's yours at?
