Okay, so how would I plug my EVAP off at the canister? I don't have any rubber caps or anything right now, so I'm considering just throwing it on ramps and getting under and spraying starter fluid anywhere possible to find leak. Sound like a plan?

Could I spray starter fluid on/around EGR to check for EGR leak?

You can use a piece of vacuum line and plug it with a golf tee, or a pencil.

Finding a vacuum leak in the EVAP system with carb cleaner doesn't work real well. It'* also not very effective in finding a leak in the EGR system.

Dang it! This seems like it'* gonna be the hardest car issue I've dealt with.

If I plug it off and it does get better...how would I try to find my leak then?

You start capping off the hoses further back. When the problem starts back up, then you know where it is.

Real quick..

You know how the 171 code has been caused by battery cables?
Would that give me my misfire? I havent checked, planning to tomorrow, but just wondering if bad cables leads to a 171 which gives me my misfire, or if my misfire causes that 171?

Now, here'* my question, I'm getting that running lean code...but I smell like I run rich.
Ideas?

Could this be caused by an exhaust leak?

Yes, if it'* saying your running lean and you smell rich, that will be a exhaust leak before the O2 sensor, or a plugged up O2 sensor.

How long on average/much might it cost to get a shop to find and eliminate my 171 and misfire? :/ Being without a car is taking a toll on me and I don't have the time to work on it the way it needs to.

Could be a lot, that code is a pain to track down. I have heard of several people correcting this problem by cleaning the battery cables.
