How are your intake gaskets? I used all kinds of cleaners in my first Stang and the results were horrendous. It had sat in a field for god knows how many years and when I got it, it was so gutless. I put fuel injector cleaner in it, engine restore, sea foam, and numerous other things. Nothing helped. Finally I developed a lower intake leak so I changed the gaskets, took a few hours cause when I got the intake on the bench I noticed the ports full of brown/black gunk. So I steam washed the intake. All good right? No. The lifter galley was also coated in the same junk. I didn't really think too hard at the time so I cleaned what u could and put it back together, said to myself I give it 3 months lol. Well true to that thought 3 months later the head gaskets let go pushed all the antifreeze out and cooked my engine. I should have pulled the heads for what it was worth and replaced those gaskets too. I blame it on all those additives. And the fact I bought a car on an impulse.
So I'm saying u prob have bad intake gaskets I guess.

Do the oil change sooner then later. As for putting it through the brake booster line I'm going to say you probably fouled some plugs. Adding it to fast will do that easily. Its a great product and I'll stand by it on anything I own but you have to use it carefully.

I found just running it in the oil helps. Never tried vacuum lines. And just in the truck in the winter. Not the car.

Check engine light? Maybe u cleaned up so much crap it fouled the o2 sensor. Seafoam itself wont foul anything up, it brakes down varnish and crud. Also, as previously stated, change it sooner than later, as in now. It thins out and brakes down your oil, you should only run it for around 30min, a day at most.

nah most likely it's just your plugs...maybe an upstream o2 at worse but go for the plugs first. besides new plugs are never a bad thing

Maybe use a better oil filter. K&N makes a very good filter. And I'm not sure what kind of mods you run but I change my plugs every year. I also use an MSD 6A on my car so it kinda burns the plugs up lol

Yes, I sea foam mine the day of or the day before an oil change, I won't run more than 50 miles with it

Ok. When I run it through, how long should I let my car idle for?

I agree. I use it in everything I own that has an engine. That and Lucas fuel treatment or injector cleaner. Really seems to be the only ones that work and are noticeable.
