Alright, one more stupid question. Last night I changed my PCV Valve. I followed the tech proceedure Bob gave me, and everything went smoothly. Today my car drove fine on the way to work, but had SES on when I went to lunch. So, I reviewed the tech proceedure, and noticed one differance. when i took the sensor off from above the PCV, it came off in 2 pieces as shown.
The tech. proceedure shows it coming off in one piece. So, is this sensor broken, is this something I can glue back together, what? Oh, the car also ran a little rough at lunch and on the way home. Nothing you noticed when in the car, but the engine sounded differant when I got out and listened in my driveway.
