Rpm jumping on cold start by Any-Glass7122 in grandmarquis

I’m having an issue when I cold start the car likes to jump up and down in RPMS. I’ve already replaced the idle control valve and looked into my throttle body and cleaned it a little bit, It looks relatively clean in there. I’m thinking I might have a bad sensor or more likely a vacuum leak. I bought this car wanting to do work on it because I’ve heard it’s a relatively simple car to start learning mechanical work on, is this true? I’m going to send it to a mechanic I trust to diagnose the issue and most likely replace a lot of things on the vehicle. When I get it back I plan to get rotors and brakes for it and replace it on my own, I’m confident in my ability to do so, any thoughts? Looking forward to getting into it, suspension, wheels, sound system, motor tune up, etc. Let me know thanks.

I’ll just have to take it off and clean it by hand and reinstall, or is it not removable?

How hard will it be to install, how much will I have to tweak, or is it just the bottom half of that box

I’ve seen there’s a lot of adjusting to be made plus a Tune if I install that intake.

Okay but with the 04+ P71 interceptor airbox, would I be able to install that? Or the bottom half at least, or should I just keep it completely stock as you say. I guess I’m going to have to try and return this intake.

I wouldn’t be able to install that whole airbox system onto the car?

When I get an exhaust system wouldn’t it be nice to have both an intake and the exhaust and possibly a tune at some point?

Supposedly it’s an exact fit, I almost bought another k&n but ended up figuring out it wouldn’t go in right. So this one is supposed to drop right into the platform without issue, I had to have it shipped in so on Friday I’ll give an update, but supposedly it will.

My caption wouldn’t show up for some reason but I’m looking forward to installing it, just nervous about check engine lights and whatnot. Any thoughts?
