Hello everybody,

I have a problem. My engine reduces power at the idle. Writes errors on misfire 6-10, and oxygen sensor BANK 2). For some reason, only the left side of cylinders 6-10 shows an error. More smoke is always coming from the left pipe. I changed the oxygen sensor, and it did not help, but there are no catalysts in my exhaust. There are people who drive without catalysts and without soft and they some time have a check on, but the engine does not reduce power.
I also changed the spark plugs and idle sensors it did not help.
My engine gives an error and lowers power only at idle and only in warm weather. Or if I was driving very fast and stopped. When the temperature is minus, the engine runs without problems. This is strange. My fuel tank also makes a noise when I open it.
I do not know what to do next. VANOS?
Any advice?

Best Rich

I think engine using more oil than normal is also a symptom of a bad crankcase valve.

i will need to try changing it soon
