okay heres the problem...i got a '00 integra' gsr..a b18c1..okae...well this is whats goin' on..when im on the highway for over like 10 minutes..after 5k when my vtec engages...well i dont knoe how to explain it...well it wont let me go past 5 thousand rpm...i dont knoe whats going on...haha ...and this happened after i intsalled a first gen VAFC.

 

probably a problem with the install not to sound obvious... check all your connections and what not

 

im thinking too also..happened to my buddies s2000 after he installed one.
