The tps or throttle position sensor could be getting flaky, but without a code I don't know if this is the case.

The map sensor if equipped could be giving false manifold readings.

The mass air flow sensor could be bad if so equipped.

I'd be guessing without more data.

HESITATION COULD BE CAUSED BY CLOGGED FUEL FILTER OR CLOGGED DIRTY FUEL INJECTORS.ALSO FAULTY TPS SENSOR.ALSO CHECK AIR FLOW DUCT TO MASS AIR FLOW SENSOR AND THROTTLE BODY. THE AIR DUCT COULD BE LOOSE OPEN OR MISSING.

95' cavalier hesitates to start and switch to 2nd gear


My friend it sounds very familiar to a TPS (throtle position sensor). Locate it by the throttle lever on the intake box.Place an ohmmeter on little brute while unplugged set the meter to 100 ohms and manually activate the throttle lever.Should read at 0 closed and 8 to 14 open . If not install a T P S unit.Cheap and readily available at most auto parts stores

Perfect Idle, no Codes, but stepping on gas causes hesitation


i would try cleaning mass air sensor, its mounted in air duct between air filter and throttle body, they sell the cleaner at auto parts stores, also as stated bofore make sure the intake pipe clamps are tight and it's not cracked, if that doen't fix it i would investigate a fuel pressure problem either a weak pump or problem with regulator
