1995 Saturn SL1 Rev to 2500rpms upon starting then it slows

I dont think I see smoke and if so its very faint. Ill replace the sensor just in case. ALSO, I replaced the PCV valve today and now it seems to idle rougher! Im wondering if I put it in wrong which seems silly even asking with how simple it was to do. I was in the process of doing the IACV BUT my husband got impatient and stripped one of the star screws so now that is not going to happen until I get it to the shop to have them extract it. Im just really bummed that the PCV valve seemed to make it idle rougher. I like to repair things on my own as a women, this sure isnt helping my case that im "capable" of fixing my own car. Any help would be greatly appreciated. Oh and the replacement air filter I put in also seems to have much wider fans. Not sure if that matters. It says that one was the equivalent to my old one.

When I start it it is 2500 then it slows to 1000-1100rpms. At stop lights its at about 1000 rpms and really pushes to get going. It literally drives itself through town. It runs great on the interstate, smooth and not much vibration. Its just the start and around town that isnt good.

When I get back from class ill check the hose. I know when I took it off it is just a straight 4in hose that is thicker and I think has a metal webbing in it. That probably made me sound ignorant. Im sure there is a name for it. I did pinch it when putting the new one on with a pliers so it may not be round. Im going to try reshaping it with it running and see if it helps the rough idle. I also checked the hoses and listened for hissing but didnt hear anything over the rattling (just beginning to) cat converter. I dont want to cave and take it somewhere and have them point out a zillion things that could but may not have to be fixed. Thanks again for all the input. The exhaust is the next major issue I want to take car of. 1st high idle 2nd exhaust 3rd interior cosmetic

I checked the hose and it does have a hunk taken out of the end that goes on the pcv valve itself. My dad put a clamp on it and it didnt seem to help.

On a side note I actually got the iacv on today! To my disappointment the car now revs to 3500rpms upon start then slows to 1300 at lowest idle. Also when slowing down from 55 to a stopsign at each down shift it revs to 2000rpms. I feel like it made it worse! Im wondering if that metal clamp my dad put on the pcv hose to stop the air hissing is too tight. Im getting a new hose regardless for it tomorrow.

Its getting very frustrating. Cleaned the throttle today too.

The gasket the runs from the manifold to out is horrible and there is a huge gap you can see. Ordered one today not that I think I can handle that job.

Smoke does come out when choke started.
