I used starting fluid and sprayed the vacum hoses. I was unable to find a leak. I can't seem to find anywhere that sells the "coffie can" canister. I've tried napa, advance, and auotzone. Any suggestions? I was able to find the black plactic carbon charcol canister that is to the left of the battery @ napa and i'll put that in tomorrow. I did find that the crankcase vent conector hose was disconected from the air intake. I fixed that. Then I cleared the trouble codes and tested again. I'm now getting 172 & 173 and I'm still getting the 332 egr not sufficent flow. More suggestions please! --jb

 

What size engine? I can lead you with a few hints if I know.
