ok, i have a 87 turboII, and the car cuts off at idle some times. and also sometimes when i try to start it after it had been running. I was told that a FPR will fix the problem, but do you guys think thats what it is? I can tell the car is running super rich, because i cant even stand behind it because of the smell. Just let me know if the FPR and possibly a secondary fuel rail will solve the problem. And would it lower the psi at all?

mods:
RB turbo-back exhaust
walbro fuel pump
HKS high flow intake
RB FCD

 

Test the BAC valve per factory procedures. Make sure the connection to the wiring harness is tight.

BAC and vacuum leaks are always the first thing to check with idle problems.

 

and would a aftermarket FPR fit onto the stock secondary fuel rail?

 

How do i check those? where is the wiring harness located. And where is the BAC located. Sorry im a noob.

 

Its on the left on the upper manifold and will have small coolant lines going in/out of it.
The manual can explain better: http://www.teamfc3s.org/main/factory...ual/1989_1991/

 

ok, but does anyone know if the FPR would make it run more lean and less rich?
