Maf Problems Or Not

[Gus134]

Hi guys,

Ive got a very intermitent problem with my RA,its a ver4 sti ra.Every now and again the car will cut out and is a bitch to start,the Commander shows AF-1 which is the air flow sensor. When the problem first happened i disconnected and reconnected the maf plug and the car started first time.

Like i say this is an intermitent problem,so ive been monitering the Air flow via the Commander and all seems well,on idle 0.80 volts with the voltage rising when driving ie 2.90 volts at around 3k rpm

There's no eratic idle or hesitation whilst driving,and the car cuts out if you disconect the maf plug when the engine is running.

The maf is the orange label type so a tad on the expensive side(unless i buy 2nd hand) just to rule that out.

Do you think my Maf is knackered?

Gus, pop in if you are passing, I have a spare Sti 3-4 maf here, if its the same unit you are welcome to try it for a while to help track it down.
