i have a 93 civic with the b20 block b16 head set up and i have a hondata ems
i brought it up to 128mph last night in 26seconds and it was just jine then to or three hours later it ****ed up on me idling at the house.
the problem i'm having is ever once in a while it will just go crazy i hooked up my laptop to it and when it goes crazy[:'(] it will not rev pass 3000 rpm and it misses till you hit 3000 the rev limiter light flickers on and off at idle and the check engine light kickes on but shows no code on the laptop the o2 sensor reads low and it idle surges like crazy

any help or suggetions whould be helpful
