hi i have a 95 Honda civic with a gsr swap in it the motor year is a 2000. It has a stock 2000 chip and my vtec does not work its just all motor. I do have a 02 sencer missing but i dont think that would do anything? I also have a check engine light on i think because of the o2 but it turns off somtimes and i have more power. I have no idea what the problem is please help.
Thanks

Why is the O2 sensor missing?

Maybe you might want to put it back if the system is looking for it. Take it to a shop and get a O2 bung welded on. Your car will run in closed loop until it's fixed. It'd not needed for VTEC to activate.

Alright thanks but then why would my vtec be not working?

I posted a link. Did you not read it? I even wrote "Read this."

oXeNo

For vtec to work, there has to be a lot of factors that come into play, and the o2 sensor could be one of them. For it to work you have to have certain engine temp or some cars, and a good enough oil pressure and stuff like that. So you not having the o2 sensor on a newer engine that could be OBD2 will probably have something to do with it. So i'd say have it put back in I can't hurt anything.

speeddometer does not work and o2 was not the problem how would i fix the speeddometer? and rpg meter works fine aswell as temp meter.

Your speed sensor is bad, the ecu needs a speed signal for VTEC to engage among other things that being said it cant be your cluster that is bad because the ecu would still receive a speed signal

yah but it lookslike just my speed meter cable is just gone is that needed at all?
