Unstable revolutions

Mitsubishi Lancer 2002  115000 miles
My vehicle does not stabilize and the engine trembles noticeably. IAC, TPS, EGR sensors have been checked and candles and coils changed but still the car does not stabilize. Sometimes, it accelerates by itself until reaching 2000 rpm and then, they start going down and up again, without ever being stable.

In my case, the acceleration was raised a bit in one of the screws near the accelerator wire, where injectors are, and it worked.
