B20 civic is hesitating
UPDATE! alright i got the hestitation and misfire problem fixed but since i replaced the o2 sensor its been throwing p0170, p0420 and p0171, it has a gutted cat so thats why its throwing the p0420 but idk why its throwing the p0170 or why its running lean. i was thinkin a vacuum leak or cuz of the ecu which is a p75. any ideas where i should start?
Hey guys, i traded my ek for a b20 swapped civic. I was told by him that the cel was only on for o2 sensors but when i got back it also miss firing in cylinder one too. it still drove and pulled hard till about a week ago, now sometimes its starting to hestitate like i put on the gas it wont do anything until im like past half throttle and its feeling really sluggish now even when its not doing that. Im thinking its not getting spark or the timing is screwed up or something i really dont know...whats yalls take on it?
edit: i was also reading something about the motor being on a closed circuit or something under 4k and it uses the upstream(or downstream which ever one is before the cat lol) o2 to get the correct air/fuel ratio, so i got another one of those but havent installed it, but if this is the problem wouldnt it being doing it all the time and not just ever once in awhile?
