OK, it all started a week ago, right after getting some gas - or so I hope thinking about the easiest explanation - while driving I can feel that even if I let my foot from the gas pedal - a teeny tiny bit - the car kinda chokes a bit, kinda even jerks a bit but very subtely - also, while idling - sitting in traffic or whatnot - I see that the RPMs are kinda flactuating - not a lot but some. Now the effect is more pronounced after I drive a while for like 20 minutes - when the car is ice cold it doesn't seem to be a problem.
Now, the idling drops are not the biggest problem - whehever I start driving from the streetlight or something - I have to press the gas pedal very very carefully - otherwise I feel the engine is gonna stall on me. When accelerating pretty steadily - I don't feel no problem.

... and finally whenever I park - the engine dies this very moment after a coupla seconds of struggling...

My thoughts:

1. bad gas (I wish)
2. since I got OTB - maybe it's the throttle positioning sensor
3. O2 sensor? Dunno - I have not CEL on.

Whatcha think fellas?

Tnx.
