within the past few days whenever vtec engages (getting on it or not) it'll hesitate like trying to stall out, so i reset my vafc competely and it stopped bogging but i lost vtec in all. so i put it back to the few settings i was sure of (6in, 6out, 4 cyl) and now when it gets back into vtec it bogs again...any help?

 

more details, before i reset the vafc when vtec engaged check engine light would come on, now that there is no vtec the light doesn't come on
