• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Car runs great but...

CEL won't seem to go off even after fixing the TPS. Today I went and got it scanned and it came up with P0121 and P0420 on the symptoms it said that a large vacuum leak can be the cause, anyone know a good place to start, which vacuums are prone to go bad? Also would like to add I don't think the cat is going out because it doesn't give off the "rotten egg" odor at all.
