Are those hard lines running to it?
Make sure they allow for enough engine movement/flex

That feels right, i also saw something about the IAC in the errors for a moment right before i re-flashed it.
I assumed it was because i opened the catch can drain for a sec...
Guess it's time to learn how the fkn iac works in this thing.
DBW TB doesn't have an IAC valve.

Is it the front panel popping up, or the unsupported main dash panel sagging?
Hint: The main dash sags because of insufficient support, leading to the cracks.

It seems to be the front panel coming up. Maybe it is an illusion is that you say the main panel sags. I’ll have to take a better look. It I know I can push that front panel down flush no problem. Then at some point it pops up. I can’t catch it in the act yet lol.
nice but I would highly recommend getting new oem heater hose T's, as those age and after being repeatedly subjected to hot/cold they tend to just snap off the plastic just gets deteriorated almost like rotten. Your idle issue may be it simply needs to relearn the idle after being worked on the iac on these is internal to the throttle body and not generally replaceable with any oem part, there are aftermarket parts out there but personally if it won't relearn I would just replace it with a new one, might help to clean the maf if that has not been done.

Long red lines down by the fuse box have a ton of flex.
Gave it a good 2 inches of space.
Also at the top, good 1/2in plus the plastic hard lines it connects to.
From there the little short pieces of red hose serve as a buffer to prevent chaffing and any rattling or buzzing sounds.
I spent waaay too much time thinking, planning, routing, bending the tube.

Well, at least you used red, so it'll add HPLong red lines down by the fuse box have a ton of flex.
