B6t idle issue help wanted

[Racespire95]

I did a b6t swap into my aspire ( gonna do a build breakdown on here sometime soon) got it running and driving trying to get it to cruise week in ocean city md this weekend lol ..... Needless to say it dosent idle, it will not start unless the throttle is depressed at min 1/8th inch once it starts it will rev up fine and drives fine. If you let off the gas completely the car will rev down n quit like you turned the key off and anything from 1/4 - 1\2 throttle the car runs horrible misses stalls and the air fuel gauge i installed reads in the lean range. The engine did this when it was in the donor car so i know it wasnt something i did haha and if i hold the Maf apx 1/4 way open the car idles perfect. Could it be a faulty MaF ? Or is there an adjustment or set screw in the MaF ? Or could i do a hillbilly repair and use something that cant be sucked into the turbo to hold the MAF open in that sweet spot?

Vacuum leak possibly? There are ways to adjust the MAF but I would look for different issues before messing with that. Can you add a pictures of the Engine Bay so people can see where the lines are run? It is easy for someone to run some of the vacuum lines to wrong location and cause lots of issues.

I'm going to try to get pics tonight the weather in Maryland isn't being friendly for people without garages lol. I did have a vac line come loose but when it did the car high idled but didn't miss
