So after I dropped off the car yesterday, they set me up with a 2017 CX-5 as a loaner. Holy crap, the throttle response was SO much better than my 2014. I know they remapped things a bit, but I feel like my engine might be showing it's age a little. I kind of wonder if it saw a lot of city driving with not much hard driving and got a lot of carbon built up on the intake valves. I went deep into the intake valve cleaning rabbit hole last night. Apparently these engines are better at avoiding buildup, but some high rpm driving helps a lot. I'll try that out when I get mine back. If not, I might check the MAF and maybe prematurely replace spark plugs.
