Hello chaps,

Maybe somebody can give me a couple of ideas on what the f@@k is going on with my soob.

I have an 05 sti, ppp, uk spec with a green filter and the prodrive pipe with a section of straight thru (to get rid of resonator).

It has run fine like this for over a year, but the other day it started playing up.

It idles way to high, 1500rpm and with a little pressure on the accelerate the revs start to jump between 1500 and 2500. Sounds like it is not firing properly. Under boost seems to pull superbly, but on normal driving I get constant stuttering. hesitation, I put my foot on the throttle peddle and it starts to splutter, if I put more pressure on the pedal my car will go but I am now hitting the boost, so my car takes off.

The engine light has come on, from reading other threads, I have tried to clean the MAF, but doesn't seem to help.

Anyone got any ideas?

Help very much appreciated.

Thanks Jez
