Engine Mechanical problem
1990 Chevy Camaro V8 Two Wheel Drive Automatic 100xxx miles

My 1990 IROC was having problems idling. I went ahead and replaced the fuel injectors with a rebuilt set af 22lb fuel injectors. This fixed my idling problem, but since I did this, the engine cuts out temporarily and then I get a surge of power when I take off from stops. I don't have any problem with this when I floor it from a stop. Any solutions to it?

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
