CHEVY HESITATION

1996 Chevrolet Blazer

Engine Mechanical problem
1996 Chevy Blazer 6 cyl Four Wheel Drive Automatic

I have just replaced the intake manifold gasket and have it all put back together and when I start the car it sounds like it gets to much air when I accelerate. What could have I hooked up wrong?

1996 Chevy Blazer hesitation

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include: Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires
