I had the strangest problem this morning.. when i entered the VTEC range after 5000rpm.. I could hear the sound of the VTEC kicking in but I wasnt feeling a push at all.. so I immediately shifted into second and I could feel the VTEC again.. Whats wrong? Is it something to do with my 1st gear only? This never happens to my car.. maybe it was a one time thing..

 

it was this morning right? was your car cold?? if it was cold, then thats why. possibly your oil also. dont know if you changed it recently or not.

 

Yah it was early morning because I just got an oil change done.. I just read another post about it.. thanks

 

If I remember well there are 3 conditions to engagement of vtec:

- oil must be present in engine (as vtec is hydraulically operated),

- oil must be hot (don't remember however the exact temperature),

- car must be in motion (it means if speed = 0, vtec doesn't engage).
