So I was just curious what others might have to say on this matter.
The post title is sort of just part of it.
Here's a list of what's been done so far:
Since then I've driven it several hundred miles, with short little 20-30 minute trips here and there, and everything seemed to be great. Good power, no hiccups/misfires.
Just two weekends ago I decided to drive it down from the shop where I keep it to my apartment (60 miles), my longest trip yet and discovered that it's not all perfect. On the way down to my apartment I noticed about 10 or so misfires or hiccups, they'd happen every 15-20 minutes or so, usually no more than a single pop and loss of power, very abrupt. I then drove it to my work the next day and it happened a couple of times. Then this past weekend I decided to drive it back up to my shop so that I could start tearing into it and figure out whats wrong. On the way back the misfires were happening a little more frequently, and I also noticed the fuel gauge would gradually go up and then down... as if pressure was building up, but then releasing. Luckily I never had a real loss of power and even cruised around 60+ mph in the thing ( that was scary ), I would even argue that the misfires only happened at lower speeds after coming to complete stops. I think it was happening more often when I'd be deaccelerating (not 100% on that), but then it would misfire shortly after taking off again.
When I went to refuel at a gas station I noticed there is a ton of pressure coming out of the gas tank when removing the gas cap. I also notice an nasty toxic smell always happening ONLY when I deaccelerate or let off the throttle. Is the pressure causing a fuel delivery issue, maybe like a bubble or something in the fuel line? After I parked it back at the shop I opened the gas cap and more pressure came out. I didn't touch it for a day and went back and did the same thing, and even more pressure came out.
Is my pig just gassy? Should I give it some gas-x?
Anyways main issues I'd like to resolve are the toxic smell when decelerating, literally feel like it burns out my sinuses... and obviously this over pressurization that seems to be out of the norm (trust me I've searched high and low around ih8mud for months before deciding to bother ya'll with this).
Hoping anyone can chime in with some insight / ideas / solutions.
As always, appreciate you all.

Here's a list of what's been done so far:
- I have replaced the charcoal canister with a generic one,
- Replaced the EVAP valve behind the driver side cargo panel,
- Reconditioned the fuel tank,
- Flushed all the lines out before putting it all back together
- Put in a new OEM fuel filter
- Replaced the gas cap
- Oh and I am pretty sure I checked if all lines related to the charcoal/evap could be blown through easily
