Sorry, I am a bit dense. In this picture, what is the unit attached to the red nipple thing?? Lower right in the picture.
Is it suppose to have a protective plastic cover?? My '94 240SX convertible does not.
I took my '94 240SX to a mechanic and he R&R the EGR temperature sensor ($188 part). And he did other things when I was not watching. I 'think' I had a cover over this red thing, but I do not even know what it is!
