ok i have a 94 civic ex with the 99 civic si b16a2 . it's idleing rough going between 200 - 800 rpms and dieing sometimes . when it's idleing steady it's at about 1200 ... also the other day my speedometer quit working and vtec wouldn't kick at all.. the as i was driveing down the road it started working again and vtec worked just fine... any ideas what would cause these probs?? also note that i am running the jdm p30 small type ecu in it. Thanks for the help guys
