hi guys, i have a problem with my car its a my99 uk turbo, first off it started to stutter under hard boost.... then it sort of dropped off boost an wont rev past around 3500 rpm an wont boost.
as soon as i open the throttle it chugs an kills the revs. also its pulling 0.7 bar of vac insted of the usual 0.5, and idle goes iratic... if i just touch the throttle it will rev normal through the range but soon as i open it up it dies... any ideas?? really need my car. thanks shaun

 

check engine light just came on... i read the code and its give 23, i believe this to be maf sensor??
would this alone cause my problems or has something killed the maf?

 

It certainly could be. If the maf isnt reading correctly the fueling could be all over the place. First stop fit a new maf

 

im on it, will i have to reset anything in order for it to work? thanks shaun

 

Replace the MAF, lambda and coolant sensor if there is no evidence of these being replaced in your cars history, all 3 are prone to failure

 

all sorted, new maf was needed thanks for the help people
