This is weird, I took off and cleaned the EGR put it back on now I hear it pinging (especially right after gear changes under a load). I have read a few threads about this and it always seems to tie back to the EGR system. I tested the EGR diaphram by blowing into to it to see if it still keeps the vacuum, and it does.
Any idea what gives?
On a side note, I also changed the crescent valve and even though it works now, I still hear a little hiss coming from under the dash (if I put my head under it. Is that normal???
