Engine Surges
While driving at low engine loads or lifting off the throttle my car bucks forward and backward. Almost as if it is not sure how much fuel the engine needs. The fuel filter was replaced 25000 miles ago and at full power and at speed the car does fine. durametric scan shows nothing and the fuel pump relay and pump seem to be working well. I can't get this one, need your help. Thanks in advance.

Drove with MAF unplugged and same thing. Cleaned throttle body and idle control, same thing. Still no codes showing up.

Do you feel the bucking in the shifter? Could be your front motor mount is wore out.

I have replaced it with the hard one about a year ago.

It is definitely in the engine. Kinda like when you open the oil fill and you get a rough engine. It is mostly when I am between 1800 to 2200 rpm and low acceleration loads on the engine.
