Having some issues with my CX-9...My wife had the check engine light come on and flash. I scanned for codes and got po203 which is injector open circuit on cylinder # 3. I cleared code and it hasn’t come back. Now when u drive at 4th to 5th gear I get a slight vibration. It almost feels Ike a shutter but I’m wondering if that injector code is related, possible misfire. I also notice the po0097 code which may be unrelated. It’s for an air intake solenoid. Any advice?
