Advice for a newbie

Long time lurker, first time poster.

Gents, need your advice. I'm not extremely technically inclined, but.........

02 GT, no mods. Service engine light comes on for the first time since owning the car(3 years). Like a novice, I open the hood and stare, looking for something. Notice what sounds like a vacuum leak, coming from rubber hose between the maniflod and the valve cover thing (pcv valve ? ) Good size crack and the rubber hose is COMPLETELY deflated when the car runs. Now, short of replacing the hose, is it normal to have that much vacuum on that hose?

Second question. Any harm in removing the screen from the air intake
thingamabobber?

Thanks a ton in advance, surely enjoy reading this great forum.

Welcome to the boards. That rubber hose you are refering to should have some vacuum, but if it's collapsing, you've probably got a bad hose. It's normal to have lots of vacuum at idle, but not enough to collapse a hose in good shape.

Secondly, removing that screen in the mass air tube (I assume this is what you're talking about,) will pretty much do you a whole lot of nothing. Being naturally aspirated, you're going to suck plenty of air with or without that screen.

I've heard that the screen was put in there to smooth the airflow so that the maf gets a correct measurement. I don't think taking it out would kill the engine or anything, but it won't help either.
Also, I would say just replace the hose.
BTW, what's with the owning the car for 3 years with no mods. You've got some catching up to do.

Def. replace the hose and visually check over all other hoses and connectors etc. the screen within the mass air sensor is there to protect the wire portion of the sensor in case debri is pulled thru the intake, a 2 cent screen can save a $200 sensor so its best to leave it in there

Thanks a ton for the great advice. In emergency tonight, I spliced a section of stiff garden hose for temp purposes until tomorrow. Will definitely get it replaced first thing tomorrow..
Makes good sense on the screen, will leave it in place.
Mods........ work, teenagers, failing porch supports, will have to wait. Missed that damn lottery this time around.

you may want to run it buy autozone as well to have the code pulled (they do it for free) just to double check things

welcome BTW
