As above car is sti version 5 which is having trouble ticking over and driving at low revs ie 1500-3500 tick over is hunting around but when driving at low revs it is like it has a miss fire or flatspots the exhaust is also all sooty and it blows out a bit of grey/black smoke when driven,when turbo comes on boost it is normal no loss of power. It is over fueling but dont know why, i have changed the maf sensor and it ran better but has gone back to how it was,also changed o2 lamda sensor but no change,took out spark plugs number 2 and 4 seem ok a little bit of soot but number 1 and 3 are sooted up quite bad so prblem is on right bank of engine it is using fuel a lot as well.Car has had slight smoking for about a week on and off it was serviced 1200 miles ago at 60,000 miles it also has full de-cat exhaust and induction kit,some have it maybe E.C.U fault or fuel pressure regulator or still a broken maf sensor or though it is new, car has also been on subaru select monitor but no fault codes were found and car was still running badly,could it be a broke injector/s the car was also left to engine brake it self down a steep hill revs went upto 4000rpm problem started next morning, any help or ideas would you please let know cheers Steve.

 

Can nobody help me with this problem or has it not been reported before any surgestions would be appreciated Steve.

 

Eh? You've already reported this problem here Steve, and far from nobody being able to help you, two of us already given you some specific advice to work with.

How, exactly, do you think starting another thread in the wrong forum is going to help?

 

You really should be a mod imo

 

Hell no. I doubt the existing mods would want the likes of me dragging their good name down.

 

By the way already tryed the advice YOU gave me or have you not read the theard properly in the first place? All i was trying to do was maybe find someone who may have had this trouble and can possibly point me in a right direction to get the car fixed,and yes this maybe in the wrong forum but like i said any help is better than no help!!

 

There's a big difference between wanting to get as many responses as possible and spamming your problem in forums it doesn't really belong.

As for claiming you'd received "no help", that's not true, is it?

 

take it to a specialist mate
