My vtec doesnt work and i am trying to figure that out but in my figuring i was testing to see if my changes work to the tec but it wouldnt kick but shifting to second it spuddered and acted like it lost some power like two ta three then kicked back and took off but till five then i shifted cuz i figured i shouldnt keep going past it if it wasnt gonna kick but what would cause it to spudder like that any one know?????

 

check ur engine oil level..

 

Are you using the correct ECU?

What CEL do you have?
