timing issues???? or ???

[anakin0303]

Hello everyone, quick question. I have a s13 with a blacktop only mod and problem is a new FIMC (no vacuum leaks). since the installed my engine will drop below 500 rpm even turn off when i stop!!! wtf

I think is the timing or the new blitz blow of valve?
any suggestion would be appreciated.

NEW....I also get a huge pop at around 2000 to 1500 rpm out of the tail pipe...? ....anybody...?

thanks

:duh:

Check and make sure everything is plumbed up right.

Recirculate your blow off valve... been discussed. Check your old 15 year old vacuum lines too lol.... Prone to crack especially near the manifold.
