tune up

[Waterloo]

One thing I found on my 2008 ProStar was that the metal lines feeding into the DPF filter were clogged with soot, rendering my tune up questionable, as these lines feed into a sensor(s), which were also clogged with soot under the body at the can. I discovered this sensor and these clogged lines after my tuneup and discovering my DPF was cracked. When I went to remove the can, and tried to unscrew the line connections at the can, they snapped right off at the can body. So, if you attempt to inspect these lines, you have been warned...
