Rough idle
So today I took off the UIM to replace the Pulsation damper, and after putting everything back together my Fc it idles like crap. I found one vacuum leak and it idles better. Any other leaks that causes a rough idle? BTW it's around 500 rpms

It's obviously because of something you removed and left unconnected, how are we supposed to know what's wrong?

Take the UIM back off and double check all of the lines.

Did you use a NEW intake gasket?

Yes, i used a new oem gasket. It drives smooth, but idles like crap.

In the morning I'll double check every thing and take off the UIM again.

If it was coming from the UIM ,you would be able to feel the air being sucked in?
