Rico,

I know this is random, but have you checked you throttle cable and gas
pedal...?  The reason I ask is I had idle issues with my subie conversion.
Last week the bottom of the pedal gave way, the rivets holding it in place
were dust...I think the pedal was going for a while, thus not allowing the
throttle cable to work properly...

I fixed it, idle issues gone...

I may be way off, but I figured I'd share

Good luck,
Jim
Wilmington, NC
