I had the CEL for EGR flow. I pulled the sensor out of the EGR tube and cleaned it really well and then sprayed some carb cleaner in the tube and then used the compressor to blow air into the sensor hole.

I have been CEL free for several weeks now and all is good!!!

YMMW.

On a side note, I replaced both front struts this weekend (Again) I did the Monroe Quik struts in 2011. I also replaced the outer CV boot on the passenger side at the same time.

Now on another side note, I have sprung a small coolant leak. (sometimes I hate old cars)
