have any of you guys had this happen? i just got my STi and i drove it up to napa california and on the way back home i started to notice it ideling funny. soon i got a check light so i looked under the hood and there a hose that slipped off of the manifold and it looks like it goes to the fuel pressure regulator. i put the hose back on for the mean while and put a clamp on it when i got back.
