starting yesterday when i drive me car, when it hits about 6k it starts hesistating. has plenty of oil in it. it only does it in high rpms. i notice that when vtec turnsover its not as loud as it used to be. you can barely hear it. in the morning it has some white smoke until you drive it for a few minutes. could it be the oil pump? any ideas?

 

Could be the head gasket. Do a compression test.

 

zmr just did one a month ago and it was fine. ill check it again

 

any other ideas?

 

Start with the ignition system if you have an aftermarket coil, like MSD they tend to do this, mine would do it CONSTANTLY at high rpms. From there, check the timing, rotor, and plugs for any damage or errosion. Be sure your fuel system is working properly. IE pump, injectors, fuel filter, etc.
