hey guys i have searched and searched but still cant find anything i have a b20 vtec in my 00 si ran fine up until the other day now at idle it wants to idle from 1000 and go till it almost dies and then back up like it has a big cam in it and when i pull out in the car it will spit and sputter all the way through the rpm range until about 4k but if i just barely let out of it and roll back into the throttle instead of gunning it it will run better any ideas
