94 4Runner hoses

Could somebody tell me what these two hoses go to or what they are called ? Need to order a couple of new ones. The smaller one is cracked, getting a little bit of a rough idle, is there anyway this could be the cause ?

they are vacuum hoses of some sort and being vacuum hoses and cracked, they definitely could cause a rough idle because the engine has an air leak which is creating an unmetered lean condition. definitely replace both hoses if they are cracked

They go to the air intake silencer box. Don't know as if they'd contribute to the rough idle, but maybe, I'm not an expert on these just yet haha. If I was you I would go ahead and replace them because yes, any hose that's cracked isn't good, but I'd also clean the throttle bottle and mass airflow sensor. My 3.0 was doing that and I cleaned those and it solved the problem. Good luck!

I plan to replace them, just trying to get a part number or description for them.

I bought a kit of divergent lengths of various size silicon hose to replace all the vacuum lines on my '95 3vze. Unfortunately, I don't remember where I ordered it from. I have some left over that I haven't yet figured out where they go yet.

I just figure its a good idea to replace any 20+ year old rubber hose that you can.

When I removed the airbox and all that junk for an aftermarket filter, I never put anything back on those hoses. Been running fine for 6 months now...
I've seen other people put little breather filters on there. The hoses are not needed to maintain a steady idle. BTW, those are EGR related hoses.

Here's the important vacuum lines diagram

Easy $5 fix, bought some heater hose. Cheaper than Toyota hoses for sure. Could be my imagination, but I think it idles better also.
