Got a CEL? When I had my vac leak (extremely cracked and dry rotted manifold hoses...lol) I had a couple codes that pointed to EGR valve.....luckily I just didn't go swapping parts, or I never would have fixed the problem
I can handle swapping out parts, but yea, the hoses into the manifold were all cracked and such from the car sitting for 2+ years....

Hopefully you emptied out that tank fast. The danger is with the stuff attacking parts in the fuel system over time.
Really? What does the 3M use as it's cleaning agent? I can't see it being any worse than say, Berryman's B-12 CHEMTOOL
Which is IPA, Acetone, Xylene, and some other stuff...lol, very stout!
No, I don't have a CEL, yet. I had a bad O2 sensor and when I replaced that I noticed that the fuel trim was high on bank 2. The engine is a Subaru H6. The most likely choices are clogged injector, vac leak or exhaust leak. I am leaning toward vac leak for the reasons you gave. Very common.
The 3M product has a high concentration of PEA as well as a few other solvents. Some solvents attack plastics faster than others.
