Yesterday I race a Z24 and my v-tec didn't kick at all on my 3rd, so I was just woundering if any of you guys know what could be wrong with my vtec..
" can it be the check engine " obd sensor " pistson " thanks

 

is the CEL on????

 

check your codes and get back with us. could be multiple things.

 

what motor? how are you so sure it didnt engage? did it engage while you were in the other gears?
