I don't sense anything wrong/hard in the pedal or braking now and I just inspected for rust and nothing. I did feel on the highway back in december when everything started that it took more more than usual effort to brake and slow down when I was going about 75mph on cruise control and that was scary.

I was about to do a smoke test since my (pickle jar + nichrome wire + inflating machine) smoker machine turned out great. I'll post some pictures. and then I'll do an injectors cleaning while running the engine on carb cleaner instead of gas, there are cool vids about doing that
