After i finished putting in my turbo kit that took me too long to make i have a problem with it idling. When i first start it up it will idle fine when i rev it and let it go back to idling it will die. I check the ecu code and it gave me a MASS air flow sensor code but what is weird is that all the vac lines are hooked up like it should be but it still dies. Any idea?

 

mabey there is a small leak somewhere
i know you said everything is plugged but sometimes we can hear or see these things
you need to go and tripple check ecerything.
and try a diffrent maf sensor just to check that again

 

Alright it stopped dying on me by itself. but i think that the ecu had to get used to a different vac on the turbo. Thanks tho
