yeah i thought at first it was IACV too, but it really only wants to dip and die when clutching in while decelerating (he doesnt know heel-toe + harsh clutch + open downpipe = not best to downshift at this point). it idles perfect and a slight throttle increase does not cause any stuttering (whereas on my KA, when i had my IACV hose disconnected while prototyping a passenger side intake, it would stutter unless i blipped the throttle...
hahaha on second hand nevermind. he just walked inside and said he found the IC pipe blown off. hahaha.
god i hate not knowing SRs like you all do.
