Low idle = choppy throttle?
So this is going to be hard to put into words but I'm going to give it a shot.
The low idle and loping is due to the taylormade exhaust on my 2008 without any additional fuel management. BUT what is weird is that while I'm on the throttle, it's fine, but once I get off, it is impossible to roll back on the throttle without causing choppyness. There's no "easing" into it. It just feels like you let off and slammed back on.
I've only started noticing this once its been getting cold.
