sup fellow prelude owners,

with my jdm h22a in my 96 prelude, im throwing some codes. 1 of them being o2 sensor code. at WOT it car just chugs and sounds like its choking and the rpm gauge won't move. also the rev limiter is at around 7000 rpms. would a bad o2 sensor be causing this big of a problem???

also im throwing a vtec soloniod valve code. what are symptoms of a "bad" vtec soloniod valve?

thanks for help,
fresh
