1997 GMC 1500 4x4 mileage: 132,000. When accelerating quickly it feels as if you are dragging an anchor, it's okay with light acceleration. Also, sometimes will pop in intake. Seems like lean fuel. Fuel pressure & volume okay. SES light was on. I replaced one oxygen sensor & light went out, but problem still there. No trouble code comes up on scanner.

Check the fuel pump amp draw because if it is starting to fail, the amp draw will be high. More than likely your mass air flow sensor needs replaced.Check the fuel pump amp draw because if it is starting to fail, the amp draw will be high. More than likely your mass air flow sensor needs replaced.
