So I have been battling this since I first did the +t on my 90 wagon. Current setup on car is as follows
1990 manual 245
90+ manifold
15G turbo in great shape
Stock CBV, no tears but it is cracking and looks bad, just checked it
Stock intercooler
stock tubing
AMM is an 020 with the meter moved to pre turbo location about 6" in front of inlet to turbo. I am feeding the vent from the breather box back in between the amm and the inlet of the turbo.
850turbo injectors
TLAO chips in both computers
Idle on the car is right around 800 RPM
T5 trans
3.31 rear gears
Ok so what I have going on is that if I get into boost and then lift off the throttle and let it go down to idle, the car dies. Every time.
If I am running down the freeway and the car is at a descent rpm but not in boost push in the clutch and let the car go back down to idle, it dies then as well.
As I have been working on the car sorting out the little things I have been driving it a little harder and harder seems as though this happens more and more. I can now make it do it on command.
I installed a new AMM a week or so ago and upon installation the idle came up a little bit at first and no more stalling....however, once LH figured out whats up, idle returned and the exact same problem came back.
Jerd said to check the CBV as that could cause this problem so I pulled it out today to check it out, it doesnt have any holes or anything in it so I put it back together.
Tried the stock chips, same thing.
So, what do you guys think?
Thanks in advance.
