Check Engine Light

My check engine light keeps coming on. My mechanic has tested the spark plugs, coils, injectors. But it keeps coming up as misfire. Has anyone had this problem? I have a 2013 CX 5 with over 191k.
 
I'd get the actual code, so that you (or another member) can reference the workshop manual. It might be as simple as actually changing the plugs. That's the most common reason for a misfire, but I'd always start with the code first. This reader (android phone) only cost $3 shipped. https://www.ebay.com (commissions earned)
 
Id be interested in how he tested. My 13 has almost 125k miles and Ive had one misfire from a coil pack failure and one due to a partially plugged injector. All injector tests came back good but replacing it fixed the issue. Is it a P0300 or 301,302,303,304? At least gives you a spot to focus. Also, check your hoses on the intake- unmetered air getting into the inlet can cause a miss. Theres the obvious hoses on the top and a tough to get to one behind the dynamic chamber.
