When I'm in gear sometimes driving down the road and I try to accelerate a bit that car bogs down for a second (almost like traction control was on, but it's not) then picks back up. It only does it sometimes and it does it randomly. I have a Kenne Bell 2.2 with all the supporting mods. What is this, how can I fix it because my car never use to do it, and should I be extremely worried about it?
