i got a 99 si. stock basically, s2k manifold, headers,intake. when v-tec kicks, it dont pull as hard anymore. first it was working fine then one day my clutch ran out and i switch it to so cheap stuff on ebay f1 and flanza fly wheel or somthing. i broke in the clutch putting like 500 miles and now when i floor v-tec is no strong. i dont think the clutch have anything to do with it but is it? any help would be fine. i changed spark plugs,oil,wires,regulator,fuel pump and theres no difference. note when v-tech kicks and hit like 6-7 it makes a noise like air is getting force out of something. maybe the values?

 

Your clutch/flywheel has nothing to do with your clutch.
Is your check engine light on? If so, check your malfunction indication codes & get back to us.

 

yes its on ill check it today but before, it was on and was still fast.

 

well i did a check engine test and it said
1.low oil pressure
2.block oil passage
3.failed VCT oil control value
so how do i fix these? i only know how to but things on and apart no fix=(.
