M42 ICV

[1996 328ti]

So I have a high idle.
I've already replaced cracked hoses.
Cleaned the ICV once.

I replace the ICV and noticed a hose was loose.
I replace the ICV anyway and have a rough idle and smell gas.
Also threw a CEL.

I haven't read the codes yet.

I'll go over everything again.
Hopefully I didn't crack the intake manifold.

Fixed.
Note to self: Don't work in the dark.

Took everything apart again and reassembled.
One problem I saw was the hose going into the ICV may become loose because I cut my own hoses to the fuel injectors and the tree is not at the correct angle.
I used a wire tie to keep it fastened.

Idle at around 800 but moving up and down slightly.
Went for a ride and within 5 minutes idle is at 1300. Now it's around 800.

Next top off the gas and check my mpg. Last time I checked I was at 20 mpg.
