I was just wondering if the check engine light affects the V-Tec. I have 3 codes an O2 sensor EGR valve and Catalyst Inefficiently just making sure that everything is working ok

 

It doesn't sound like everything is working ok.

 

You can still have VTEC. Not all codes will put your car in limp mode. I wouldn't think those would put you in limp mode either. Do you plan on fixing those? What mods do you got?

 

I do plan of fixing them but I just haven’t had the time lately right now all I have is a header and exhaust but I am trying to find a good block that I can start working on so I can build it up

 

I thought an O2 sensor would cause that....

 

Fix ur problems man, your gas milage is probably terrible right now. An o2 sensor for me was $50 and use some carb cleaner to clean ur EGR.

 

I know about the EGR thing but everytime I get a price on an O2 sensor its like 200 bucks

 

My VTEC activated fine when my oxygen sensor was dead... Check your oil level.

 

I always do and my gas milage isnt that bad either i get like 28-29 on the highway

 

yeh my o2 sensor is out in my h22a4 accord an my vtec still works, but my gas milage is only bad when i get on it but i drove my car to houston i got 400 miles on a tank of gas, only had to fill up once an once on the way home.
