So I finally had a day that I could troubleshoot. I got the vacuum meter hooked up and following some different videos I show that vacuum when warm is below 20 and that around 2000 RPMs it drops. Furthermore, when I started it on a cold day, so little vapor seemed to come out of the tailpipe. Also, the front catalytic convereter always smoked a little from oil but now that thing smokes like crazy making me think that it is even hotter than it was before. I know that's not the best indicator but does seem to fit too.
So I am trying to figure out what to do. If I wait a few weeks, I can try to drop the exhaust and confirm it, then what? My sense tells me that it is the front catylitic converter. How would I confirm this? Get it apart and look through it?
There is supposed to be a good muffler shop here in Ashland. Should I just take it to them and see if they can cut it out and weld in a replacement? Should I replace with a new front y/pipe catalytic converter purchased online?
What do you guys think?
