Hey Everyone, For a little while now i been trying to get an issue resolved with my car. ... its a stock 1996 Integra GSR b18c. And somewhere around 7 months ago i had my clutch replaced and noticed that vtec in my car only kicks at 5,800 rpms .. and i found out that my intake manifold has a dual stage system and that the first stage isn't engaging ... is there anyone else out there that might have any suggestions as to why my vtec isn't kicking at 4,500 rpms .. oh yah and it eats oil like there's no tomorrow since my vtec hasn't been working right.... so i've been driving it like a granny I'd greatly appreciate any feedback anyone could give me.

thx.
