What Causes Limp Home Mode??

What Causes Limp Home Mode??
My check engine light came on and has stayed on and now the engine wont go over 3000rpm,it seems to cut out when the turbo hits 0.5 bar,does anyone know what causes this or is it a case of plug the diagnostic thingy in and see what it brings up??
I'm thinking it could be the MAF sensor as for the last month or so i've had a wandering idle when lifting off the throttle,it dropped to about 500rpm and then went up to 1000rpm ish and then back down again.
Cheers in advance Paul

I have a 23 which is the maf sensor and a 53 which is the fuel pump or circuit,is it worth uprating my fuel pump?? i have a tek 2 ecu running at 17psi if that makes any difference.

My RB5 did this a few months back. Turned out to be the MAF sensor.
It went into Limp-home mode twice, but after switching the car on/off it ran fine again. Then I noticed it would pulse when accelerating and showed some flashes on my knocklink.
Decided to drive the car very gently until I could check it out. Then went to Oz for 6 weeks and finally managed to get a replacement from my Dealer after a 10-day wait.
If it is the MAF/fuel pump don't go thrashing the car.
