SES ligh came on tonight

[ekvals]

Hi.

I've had my SES light on a couple of weeks now, which i assumed where caused by a faulty ABS sensor on the right side wheel.

I replaced the sensor today, and after a while the SES light went out.

After driving the car around for about an hour, i stopped, and noticed that the car was'nt running smoothly while idling.

I entered the test mode and saw from the digital rpm that it was running between 650 and 850.. In addition there was some vibration / shaking that could be felt sitting in the drivers seat.. After a little while, the SES light came back on...........

While driving the car i cant tell that anything is wrong. The car runs at it should.


I had the CCV and head gasket issue about 2 months ago.. It was fixed and worked fine till about three weks ago. After a really cold night, there where pressure building up in the engine, and some oil and air escaped out via the oil refill cap.. I let the pressure out of the engine, and it seemed i where lucky since i could'nt find any oil leak, and the engine did'nt build any pressure.. Since that incident, there has not been any idnications that the CCV is'nt working as it should..



Also, i had some rattling sounds on top of the engine on the drivers side. I have another post on the forum here, and the DISA valve was suggested to cause the rattling sound. It seems now, that the rettling is gone...?

Any thoughts..?

Could it be that the DISA valve failed completly.? Does it sound like something with the CCV issue could cause this.? I guess the sensor issue would'nt cause any of these symptoms.?
