bad afpr?

[epix]

Noticed yesterday while trying to tune the motor that when I set the fp to 50# w/o the vacuum line attached. Soon as I would put the vacuum line back on the engine would die. I tested a few different fp settings but anything over 40# would cause the motor to run rough and die in a short while.

Could my afpr be broke? It is a kenne belle afrp that I bought used a couple years back and it sat in storage until last fall.

mods are in my sig, 50lb inj, ult chip, no egr

Re: bad afpr?

check for fuel in the oil or the vacuum lines.also reset your iac to make sure it's right.

Vac leaks?

Re: bad afpr?

50 psi fuelpressure seems a bit high for the 50 inj. my guess is, its dieing because it´s runnig to rich - i had the same problem when dialing in the 50´s for the first time. i ended up running 32psi fp.
i also had to adjust the throttle-stop screw to stop it from stalling when idling.
