try checking and cleaning all of your grounds and the battery terminals.

Is there a CEL?

Check and make sure all ignition wires are on properly. Check the condition of the dizzy cap and rotor (the posts inside the cap and tip of the rotor).

Could also be glogged fuel filter, bad injector(s), dying fuel pump, main relay...

It might be a sensor issue.

Check your TPS.

Anyone know where can I get a brandnew tps in gta area?

Why not test it first? Don't just blindly throw parts at it.

Throttle Position Sensor

If it's an intermittent problem, it's gonna be hard to diagnose. If you're like me, my cars always behave perfectly when it actually comes down to me opening the hood and trying to find the problem. LOL. I'd say find a used one or something or take one out of a car that works and install it in yours and drive around a bit. Realistically not the best suggestion but, we all have mechanics we trust and/or have personal relationships with so I'm sure you can find one to try.
