rough idle when engine is under load S80 2000

posted by  someone claiming to be BobG. on  Sat Mar 9 07:54 CST 2002 [RELATED]

I have rough idle when the trasmission is in drive position and AC is on. Engine's rpm are cycling between 500 and 800 rpm in short cycle - half a second. Anyone else had this?

I think that`s normal when engine is under load.But i would check Air Mass Sensor if it is common problem and clean it up if it is dirty.But be careful if you`ll clean it yourself you may damage it.This is very expensive thing.

Could be a numbe rof things but I beliave there is a download for RPM fluctuation from a/c compressor cycling. It might apply to your vehicle.
