Running rough with P2316, P2319
I'm currently seeing an "Engine malfunction. Reduced power" and/or "Increased Emissions" message with really rough riding conditions. I suspect I'm getting intermittent cylinders firing. I pulled the codes and received the following :
I want to make sure I'm replacing the right coils. Does anyone know if the the cylinder letters on the codes translate to the cylinder numbers? I doubt it's related to firing order but who knows? Also, I'm thinking P0111 is caused by the other two errors but I'm not sure about that. I thought it would be wise to resolve the first two errors and then see if the third error went away. Unless someone has other suggestions? Last edited by ///MTex; 06-18-2016 at 09:21 AM.. |

I should have posted the solution to this earlier, but I thought my situation was unique, especially since no one else seems to have had the same issues. My car may have had these issues because I had to replace my engine about 1.5 yrs ago due to rod bearing damage. Since then, I've had to deal with a number of issues, this being one of them.
The codes indicated there was a problem with the coils. I tried new coils, but the problem didn't go away. I finally took it to my local indy shop. They worked through a similar diagnostic test, but couldn't find anything wrong w/the coils. From there, they decided to focus on combustion rather than ignition, looking for air leaks or poor fuel delivery. Eventually, they found a couple of the injectors were not seated properly. They raised and cleaned the injectors and ports, reseated them properly, and this solved all of the problems. I can only theorize that this problem was due to complications of the engine replacement so it may not be the same solution for you, but the diagnostic process may be helpful in resolving your issue. |
