2003 ISX suggestions needed

[DDlighttruck]

Its already cleaned and back together. I chickened out on the metal tube leading to the exhaust pressure sensor, I know how to do it, cut the tube off, heat it up, use a ratchet and a socket to spin it out. BUT if that doesn't work, then on a Saturday I'm stuck. I'll leave it and let a shop do it when there is time. Then if it doesn't work it's their problem. I need to go to work on Monday.

The EGR differential tomorrow, and look for the delta P.

Thanks for the heads up on future repairs Waterloo
