Most likely it's your idle air control valve the pintle inside builds up carbon on it. if you have access to a scan tool hookup to the dlc and you can test pintle % opening.

Nissan pulsar 1999, surging. Power and revs wave up and down quickly. What could this be?

  1. Fuel delivery problems (bad fuel pressure regulator, bad injectors, clogged fuel filter, etc.);
  2. Defective idle bypass (Idle Air Controller);
  3. Bad Throttle Position Sensor (TPS);
  4. Defective Engine Control Computer;
  5. Demonic purple gremlins from space (don't make them angry).

I have a 2001 Toyota Corolla. The revs fluctuate whilst idling.

could be a bad TPS or stuck, bad, dirty idle air control solenoid (IAC). check fuel pressure and check for vacuum leaks after the air flow sensor. more info is needed because what you describe could be many different things or a combo of different things

When I start the car it stays at 2000rpm for a few moments then drops down. I'll drive for a few minutes then put it in park and it revs up and down.

idle air control valve is bad replace it. at start up choke control runs till warm up while driving throttle opening controls engine at idle ,the idle air control valve.

Engine continously revs while idle? And battery light on? Is this a combined issue or separate issue and how costly?

Idle problem:
-you might want to check your coolant level. Low coolant or air in the coolant system can cause idle jump up and down.
-also a bad air control valve can cause idle problem.

Battery light:
-usually cause by a bad alternator(replace alternator)

Idle problem,engine revs up and down

This may be due to a bad idle air control valve, or being low on coolant will cause this problem also. the only other thing is the power steering preasure switch, this switch when it goes bad it causing idle to go up and down, hope this is helpful.

When in park honda odyssey revs up and down between 1000 and 2000 RPMs

is the check engine light on also? it sounds like the idle air control valve is bad. this controls the idle of the vehicle. when it is stuck open it causes too much air into the engine and causes it to rev. when it gets to a set rpm, the pcm cuts fuel. then it turns the fuel back on, then the engine revs, then it cuts fuel........code p0505 will prob be set

Rough idling and choke

the only thing that can cause this is maybe you have a bad planium gasket but before changing this you could also have gotten some bad gas cause most gas have 12% water or more so try STP gas treatment first
