i have a b18c1 and it just started 2day.. when vtec comes on it feels like vtec is comming on and off but its not its just hesitating and misfiring...i have a street tune so im guessing the a/f ratio should be good...any ideas?

 

might need to be re-tuned at WOT. Any cel?

 

nope...im gonna check my timing 2morrow..it may just be something stupid

 

it might not have enough oil, it'll do tht. mine was doing it untill i got to thinking about it
