Hi,

let me explain you my problem: for the last 2 years i've had a big problem with my idle, it was fluctuating en quite often engine stalled when driving (really it stalled when slowing down to stop). my mechanic checked the soleinod, the MAP sensor, the plugs and the ICV.
i've had all those parts but the MAP sensor changed.
now no idle issue (honestly very very little fluctuation since parts change) but now i'm facing a very annoying problem; when engine is cold and i fire it he stalls immediatly, to avoid this when i start the engine i put the rev at +-1500rpm for 2-3 seconds, then it runs fine but can stall 1-2 till it's really hot.
when hot it starts immediatly and don't stall.
i've been told that the problem comes from the MAP sensor.
can you give me some advice because it's really driving me crazy!
thanks
Daniel

 

no one can give me some help??

 

The MAP sensor hardly affects drivability on a Subaru. I think it's only used to determine when to cut fuel if you overboost. So I don't think it's the MAP sensor.

It should be either an intake leak or a MAF problem. Have you tried pressuring the system through the turbo inlet to look for leaks? Also check that the piping between the MAF and turbo is leak free and try out a known good MAF.

If there is no improvement from that, check your AFRs, you could be running lean (the leaning out is the reason the engine stumbles and can go off if you have an intake leak).

 

Can i buy the maf sensor plz.

I don't think there was a maf sensor for sale....even 6 years ago
