yeah, i've finally got my 92 gsr'd hatch runnin, i've got the b17a1 and im runnin it right now w/out a knock sensor cause mine broke and im buyin a new one in a few days, but i've been drivin it and sometimes it lags real bad and sometimes its fast as hell...i was think maybe the knock sensor could be causin this but i didnt know if a knock sensor would do that much damage? and i was thinkin maybe i have clogged injectors or something like that but i mean i'd say about 75% of the time it lags real bad and sometims it hauls...
