Question: Oldsmobile Aurora

I have two questions.

My car: Oldsmobile Aurora 2001 V8
When I'm driving my RPM's shoot down to 0 then go right back to normal, even when my foot is on the pedal, and I can almost feel it pause. It shuts off while im driving it too, freeway driving and just through town, sometimes it cranks over but wont start until I wait 1-5 Mins then it starts, sometimes it wont even crank over, then I wait again and it starts up.

May be the Crank Position Sensor is not working well. It sends out the RPM signal to the PCM. If it is bad, there is no RPM signal, and the PCM will not command the injectors to fire.

It could also be a battery charging system issue. If charging voltage isn't stable, the vehicle will do all sorts of strange things. You should have the alternator and battery tested first.
