The MAF fixed it I got a new one for $78.00

I have a 97 chevy tahoe that has hesitation at low rpm's as soon as apply more gas pedal the hesitation goes away. My check engine light is on and registers a misfire. I've replaced plugs, wires, cap, rotor, and fuel filter. I running out of ideas

Please provide more info. What code numbers are being displayed?

Are any codes logged as a History code?

Have you reset the ECM and the SES light returns?

Is your V8 a throttle body type?

Do you mean that you are experiencing hesitation from a stand still throughout 1st to 2nd gear and then the hesitation lessens?

My problem is a 97 Tahoe 4 door 4x4 , when at idle have no issues but as soon as you put a load or apply gas to it , it bogs down and falls on its face . Have check mass air flow, check fuel pressure at rail I'm getting around 52 lbs, when running same presume . If you put starter fluid to to it when it is hesitating it seems to help. Any info would be greatly appreciated. Thank you

Are there any trouble codes indicating a lean fuel mixture?

Also, fuel pressure should be between 56 and 66 psi. Your's is a little low. Have you checked for a partially plugged fuel filter? Have you confirmed the regulator is good and working correctly, not sucking fuel into the vacuum hose?

my 95 tahoe has a bit of a stumble/miss at the top of the gas pedal, when i get past the top of the pedal it seems to be fine. I have replaced the plugs wires cap rotor air and fuel filter pcv valve and the tps. it seems a little better but still has that. Also when it idles sometimes it has a bit of a missfire/ stumble. I also checked the egr valve and it holds but the travel upward is not very smooth. could it be the egr even though it holds in place?

If the check engine light has come on, have the computer scanned for codes. Also, check for tune up. You may need to check engine compression due to the miles on the vehicle.

Try cleaning it out and see what happens-https://www.2carpros.com/articles/engine-misfires-or-runs-rough
