Rough idle Oldsmobile alert
02 only in drive
Check the codes. If it's the 3.4 vs then a good chance either a lower intake manifold gasket leaking or blown head gaskets as that is very common on that engine and is more noticeable in gear. Honestly hard to answer with specifics without more details including any codes stored.

What is causing my Oldsmobile Alero to shut off after starting?
As for the lights being on many GM products do that right after the key is off but if you open the driver's door they should go off. Not sure if that model is part of the ignition switch recall or not. Due to numerous ignition switch problems I would have the ignition switch replaced. The key cylinder IS NOT the switch. The key lock cylinder operates a rod that in turn moved the ignition switch to various positions. Battery must be disconnected and care taken not to deploy the airbag while the switch is replaced. I think I would go with a after market brand such as Delphi rather than another AC Delco factory switch.
The engine shutting off after starting may also be the ignition switch not moving to the RUN position properly. Before doing anything else I'd replace the ignition switch then go from there if the two problems are not cleared up.

2.2l. Where are coil packs located on engine?
quick way to see if a coil pack is firing with out using a thousand dollar analyzer is to use your twenty dollar timing light , just connect the power clamps as normal , but move the pick up to each branch pigtail wire to each plug , and ck to see if light flashes in a normal pattern , if it no flashes or don't flash in a pattern then that coil pack or spark plug is bad (id try the plugs first )
