91 Galant VR-4 "Slutty Paula"

^Thanks mike,

Now I've just gotta figure out why it's got such crappy idle surge. I checked out This Page on VFAQ and tested my ISC and got 38ohms for each pair of pins, so I think it might be something else. Basically what happens is when I stop at a light or something, the rpms will rev up and down like 300rpms consistently. Any advice?

have you done a boost leak test? i know i know everyone tells you that and im sure you have but its a start, also have you checked the biss o-ring if its the origanal it might fall apart when you touch it like mine did lol.(if you figure out what it is let me know mines surges sometimes too)

haha ya know, I haven't done a boost leak test! I've been without a turboed car for so long, I totally forgot about that joy. Could you be more specific about the biss o-ring, not sure what you're talking about.
