Default Na not idleing after teardown

I took the intake manifold off my car to clean up around the area
Now the car doesn't seem to want to idle. It runs good and smooth above idle but it just idles kinda funny. Like i have aggressive cams or something up and down real fast from like 500-800rpm, and that is if i hold the pedal to make it stay running.
I also hear a hissing from the engine too.
What could be causing this?

BTW, no codes except the usual 52, wich was fixed but the wires came loose. I only tested it when it was off tho.

Vacuum leak. Find the hose thats leaking and replace it. You can do this by running ur fingers along the hoses and if the hissing gets softer or stops you have found the hose that is leaking. Check the intake hose first, thats usually what cracks and makes the car idle like crap. If everything is fine, check to make sure all connections and clamps are tight.

Sry it kept saying messge too short.
Anyway, it was something that goes into the side of the manifold that is held on by two bolts near the firewall. I'm not too familiar with engine terms so i couldn't tell you what it was.
It was about 1.5 in wide.

thx

"something that goes into the side of the manifold that is held on by two bolts near the firewall."

That would be the EGR valve.
