Stock 82 turbo, has been a daily as long as Iv owned it and always runs great.
Started cutting out and running progressively worse over the course of a few days.
Fires up and idles perfectly, but wont really rev past 1500rpm.
I can get it to go higher but its when the boost gauge hits 0 or positive pressure its cutting out,
not getting enough fuel and will pop out the intake.
The timing is set to 20deg on the dot, brand new CHTS, O2 sensor, plugs, cap, rotor, coil, fuel pump, AFM is cleaned and wiper arm set on fresh carbon, all my electrical plugs are either brand new or cleaned, I can hear all the injectors firing ect.
Have done all the FSM EFI related tests and now Im starting to get stumped.
Iv even tried moving the AFM gear rich 4 teeth as a test just to see what would happen... no change.
(I normally hate touching that because it tends to just be a band aid fix for some other issue)
When I have the air box off and rev it to where it starts to cut out and have a friend push the flapper open a little more with a screw driver it goes away and revs strong like it always has....
... Really not sure what to look at next, Iv never had an issue like this with any of my L28et cars.
