Just bought 93 Olds 88 (V6 338) for teenage son, appeared well maintained, 1 owner. #1 Now seems to hesitate at slow speeds and up hill - higher speeds ok. Put new tank of 93 octane in, but same issue. #2 He put in it in Reverse to park and it stalled and then engine smelled like smoke. Ideas??

Lack of acceleration,chugging,hesitating,jerking,bogging,misfiring etc. could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
