Alright well the replaced engine may only be approaching 100k but the rest of the car is approaching 200k and stuff isn't what it used to be.. Anyone had problems like this / solutions?

Driver side window will not go down all the way 30% of the time. it will just stop and wont go down any further. Some days works fine, some days goes down 90%. No clue here.

Rattling noise whenever I hold the brake, it sounds like something underneath (I need to get a lift). I've checked engine bay, sound does not come from there.

Engine still pulsates a bit, knock sensor is going, but I using premium fuel now, still believe there is a vaccum leak since cruise control doesn't work / I hear a "sssssss" noise but if i reverse a value noise goes away. The noise comes from something attached to the air filter box towards the engine.

SRS light will not go off, it throws error "right seat belt tensioner" I can clear it but as soon as i start car it comes back again. Any tips on what to check on?

Thanks guys, I'm just getting paranoid, and the cold weather season is here so not too bad to work on a car :-)
