I cleared the codes with my code reader, but they come right back at start up. Put the original plugs back in and cleaned connectors at the coils and PCM. No change. Same codes. Took it for a ride and again, ran fine. I think I will try to put some miles on it this weekend and see if they clear on there own.

I had swapped the coils around with no change in codes. I disconnected the battery for 1 hour and no change in codes. I will reinstall the original plugs and clean connections at the coil with a plastic safe electrical contact cleaner.

My wife usually drives the car at least once a week for short trips ( less than 30 miles ). I always felt the car accelerated poorly, due to a small motor in a large vehicle. There was never any hesitation or misses. I kept the original plugs and I may reinstall them. I drive a 2008 Chevy HHR with a 170 hp 2.4 liter running iridium plugs (oem). I thought that would be an upgrade. Like I stated previously, the vehicle runs fine and acceleration seems smoother and quieter. I'll due some more driving with it to let it go through some start cycles and see what happens. Thanks for the feed back.

My wife's 2014 Journey SE 2.4 liter had the check engine light come on recently. I pulled the codes and got P2305 and 2311. Cleared codes and they returned on next start up. Both codes were for Secondary resistance on Coil B (2305 no. 2 cyl ) and coil D (2311 no. 4 cyl.) The vehicle was purchased new in November 2014, and has 5300 miles. I found it improbable for and engine with less than 6K miles to have coil or plug issues, but I pulled the coils and checked resistance. All coils were reading the same resistance across terminals and from terminal to spark plug contact. The no. 2 and 4 plug resistance was lower than no. 1 and 3. I replaced the plugs with NGK Iridium gapped at 0.44. Still getting codes, 2305 and 2311, but engine runs fine, accelerates quicker with no hick ups. I did swap 1 and 2 coils as well as 3 and 4 coils to see if the codes changed. No change there. The vehicle is no longer under factory 36 month warranty. Any suggestions would be greatly appreciated.
