Default Problem with 1993 Bonney, part 3 (+)

Hello!
Thank you for your patience in reading my topics .
Let me to remine you the simthoms.

Bonneville 1993, 3.8 SCh.
New spark plugs NGK Platinum, new Tayler wires, new MSD coils, new O2 NGK sensor.
New fuel pump AC Delco.

Problem is starting at full trottle both at idle and at driving. The more loading - the early it starts flaping in the intake manifold with loosing the power. Releasing the pedal I solve a problem. The problem has started just after I load my fuel tank at unnown station.
There are no codes at PCM memory, EGR solenoid weems to work correctly.
Tomorrow I will try to clean MAF sensor. PLease advise me what else should I do?
May be cleaninig injectors?

Thank you for any assistance.

I very need to get back my Bonney'* power.

Regards
Vitally.

If you received bad gas, you could have problems somewhere in the fuel system, anywhere from the fuel pump, the fuel filter, to the injectors.

The fuel filter is fairly easy to change under the car. You can also try some injector cleaner in the gas tank, or have the injectors professionally cleaned.

I can't say for sure that it is the fuel system, though.
