Just having an issue with the 2009 CX-9. Wife reported a check engine light and running rough. After work I read the OBDII codes and got #5 fuel injector open error. Starting again from cold it ran fine so I erased the codes and started driving home. After a stop to eat (warm engine?) I got the CEL and the code again. Was able to gently drive home minimizing vibration by using lower gears.
Questions:
1. Is this an expected failure at 10 years and 125000 miles?
2. Since it is showing an "open" does that indicate an electrical vs mechanical issue with the injector?
3. I think #5 is on the back row so I will need to remove the air plenum--so--should I go ahead and replace all injectors at one time?
4. Is it worth doing just a unplug, spray with DeOxit, replug or should I plan on just replacing the injector (s)?
Any experience or advice appreciated.
