maf sencor help
jay_russell so am i looking at the vacum sensor.... maf or air tempture maf.
what one is the maf sensor
If it's an IS200 then you don't have a MAF sensor, you have a MAP sensor (vacuum sensor on that diagram).

What extra kind of MAP do you have to handle the turbo ?

29-09-2018, 04:34 PM #16it's only started when it got cold over here. -1 or so. so thats why i'm not sure whats going on. have looked over the car and all the hoses seem to be ok.
When it's colder the air is denser, I don't know if that is going to affect things for you at all. Normally that's a good thing in that the denser/colder air will burn better, but whether it's tipping something over the edge in your mapping ? I don't know. If there's another MAP sensor it's probably connected into the same hose as the stock MAP sensor.
What error code was it exactly ?

29-09-2018, 04:39 PM #17ok that sounds odd. That's the kind of thing that happens on a supercharged car if the black box goes wrong, i.e. the stock ECU sees too much boost.

29-09-2018, 05:22 PM #20Does it happen all the time now, i.e. you can never get past 3000 rpm without going into limp mode ? Or is it intermittent, and sometimes works fine ?
