Default reduced engine performance

i had a message saying reduced engine performance on my car on saturday
i sat in the car with the ignition on for a while before i started the car and when i started it the message was there and the car was very reluctant to rev. i turned the engine off opened the bonnet and unpluged the afm wireing from the airbox. i plugged it back in then started the car and everything was fine again and has been all weekend.
what has been the most common reason that people have had for this message. car is a 2001 s60 t5
i have had a search and it has thrown up etm and afm/maf as the main ones

I had the same problems with my Volvo XC90 (2004 AUTO).
Loads of error messages:

Reduced Engine Performance
Anti-Skid Service Required
Engine System Service Required

Manual shift did not work
Engine just died sometimes - hazard lights did not work when engine died!

I searched a lot on this forum and knew it was not computer related.

It was simple a malfunction of an Air Injection Relay.

I bought a new one ($20) plugged it in and a problems where over!
