- I have a 2013 Mazda CX-5 Grand Touring automatic transmission with 147,000 miles. It started misfiring and gave me codes P2308 and P2311 ignition coil secondary circuit faults as well as misfires in cylinder 4. I replaced all ignition coils and spark plugs and all the codes went away. The car ran great for about a week then it started misfiring again but this time I only got generic misfire codes. Nothing else. My friend suggested new fuel injectors so I have some on the way. What else do you recommend? I appreciate your help.

The first thing I would do is run some of my friend Bernie's ATS fuel cleaner through the system as it will clean up valves and fuel injectors and it might fix it entirely. When they do misfire from the problem you had before, of course it can clog up stuff with carbon and cleaning it out. Might fix it rather than buy an expensive parts
