The engine is working rough mostly at cold. It is much better at hot.
I found a lot of oil on the spark ignitions. The scanner gave the codes
P1336
P1337
P1338
P1339
Thank you for your time.

Hi,

This vehicle isn't offered in the US, but I will try my best to help.

Looking at the spark plugs leads me to believe there is oil getting into the spark plug towers. If that is the case, that can cause a misfire, P1337 and P1338.

The other two codes you have are both related to the crankshaft position sensor. You have an intermittent signal issue.

The first thing I would suggest is to locate the sensor and check for wiring damage or a connector issue. If everything appears to be in good condition, then I would replace the sensor to see if that eliminates the issue.

Here is a link that explains in general how a sensor is replaced:

Let me know if this helps or if you have other questions.

Take care,

Joe

The problem was in the coil.
