yeah I have a 97 Honda HX coupe with the JDM B18C GSR swap and was wanting to know somethin, uve seen my friend "tehjustin" post things on here before about my car

Well before my car was jumping rpms between gears and idling kinda high and was just throwin the O2 sensor code, well now the only thing its doing is kind of idling high, it stays about 1800rpm until you drive it for a while then it goes down to around 1300-1500rpm, its still throwin the O2 code, but now my vtec isnt working

Weve checked the codes plenty of times and reset the ECU, and I even been letting it warm up for a while, the vtec was working at one time but after I changed the TPS sensor and reset the ecu it doesnt seem to be kicking in now, but nothing seems to work, if anybody would know what the problem would be let me know
