Hello,

Having rough runing. Durametrics scan this codes. Seems the problem can be cylinder #1 misfire. What can be the possibles issues? Spark plugs? Coil #1? Anything else?

 

Thanks in advance

The P0130 and 0150 codes are both potential wiring harness issues (shorts or low voltage signals).  If the car was in my shop, I would make note of the codes and then clear them all, and then take the car out for a run to see what comes back.  It is unusual for both O2 sensors ahead of the main cat to develop problems simultaneously, so it could be a harness problem rather than the sensors themselves.  If the 0130 and 0150 codes return, I would check the sensors themselves for the correct voltages; if they check out, I would start looking at the harness for shorts or other issues.  The misfires could be connected to the sensor issues, or a coil or plug problem.

Thanks for reply, 

I cleared the codes and reappeared again. What mean the P1313? Can a Single coil problem cause the simultaneous O2 sensor bilateral?

Not really, the misfire may just be a separate issue, but a misfire on one bank cannot cause an O2 issue on the other bank.

I have an update pictures of cylinder #1 coil. Coolant reservoir hose might be the culprit.

I cannot understand why this hose was there. My last mechanic replaced the waterpump and coolant cap not too many miles ago.

I made a purchased same brand "beru". I will attempt to do it my self and reroute the hose. I'll rescan and report results.
