I replaced the charcoal canister, not with electronics, I bought just the canister and transferred over all the pieces. I also replaced the breather line with built in filter. It takes gas now but the idle stumble is still barely there but much reduced.

I was also running a cracked (Turner) exhaust and switching back to stock helped a bunch too.

I’m convinced it’s a vaccuum issue but haven’t found where exactly. It’s most troublesome for me 80-90 degree ambient so when temps get back there I’m gonna pick up where I left off. Hope this helped in any way.
I was thinking it could be with the charcoal canister, but the inline fuel filter I’m not familiar with. I’ll have to look that up. It does kinda act like a vacuum leak I’ll have to smoke test that too. I appreciate the leads.
