Need help from experts here.
87 GN stock with 87k miles
Parked the car 6 months ago ran great, started up a week or so ago and when it hits 3000 to 3500 rpms it starts to cut out, then turbo dumps out the waste gate.
I tried,
New Walbro 255, new sender, new gas tank. no change
New MAF sensor (aftermarket) no change.
New plug wires no change,
New coil a few years back.
I thought I was lacking fuel so I installed Walbro, I have 45psi plus all the way up to the cut out/engine sputter, so eliminate the pump as the issue.
Is my turbo shot? Any thoughts on helping me diagnose is appreciated. I am lost at this point.
