hi my m8 has got an s2 rs turbo that he has had the engine fully rebuilt with stage 2 head and the works the problem is it wont run right u start it up and it stalls and wen u get it to tick over it wont rev and it sputers we changed the airflow meter cause we were told it was nacked and its beter but still the same if u plug the airflow in it revs but wont tick over and if u unplug it it deos the oppisite the car ha had pretty much everything new has any1 got any idea wot it is cheers

 

hi mate got exactly the same problem on my frst changed almost everything and can't find the problem if u fix it before me send me a message mate and ill do the same for u

 

is the mixture set up correctly? and the timing is correct? sounds like this could be the problem. even the breather system could have a air leak in it? so many different things it can be but often it is the most simple things that are at fault.

 

ive just had this problem. wouldnt tick over and when i pulled out any of the breathers it ticked over fine.

it was the mixture screw on the meetering head that needed adjusted as it was runing far to rich on idle.
