Why are you unplugging the MAF when the engine is running? That's an easy way to damage it.

When you say it revs up to 2000 and then back down, does it do this all the time, or just when the engine is cold, or just when it's hot, or..? Also has this started to happen all of a sudden or has it come on gradually?

As a general point, btw, anyone buying a 15 year old high performance, low cost car, and who doesn't expect the odd hiccup, is being a little unrealistic.

Thought you might have. For what it's worth that "advice" is complete bollocks. Doesn't tell you anything useful about your MAF, one way or the other, and as mentioned can, if you're unlucky, damage it.

The advice you've already received about cleaning the ISCV is the first thing to do. If you're still having problems afterward let us know and we'll go from there.

i found that my car ran alot better with the maf unplugged when it was fecked, just went into limp mode and ran ok. with it plugged in it did alsorst of strange things

That's not what we were talking about.

The specific old wives tale Dan seems to have been following is the one that goes "Start the engine, unplug the MAF. If the engine stalls, the MAF is good, if it doesn't, the MAF is knackered"

It's that ^ specific procedure I was talking about. It's bull, proves nothing, other than the willingness of some folk to believe anything they read on the internet without thinking.
