Alright I'm not too good with electrical stuff so I'm gonna need some good ol' HT help.
1995 EX stock

Sry for the long story, I like to be descriptive
This just started today, on my break I came out to my car and went to start her up. I turned the key to the II position and nothing came on, none of the gauge lights or anything, I don't even hear the fuel pump prime, just a quick flicker of the little lights on the climate control. So I'm thinking "Great, dead battery". I try the headlights and they come on just fine along with the dash lights, a little odd that those worked. So I move the key to III and it starts up just fine so I'm thinking "wtf???" mainly cause I didn't hear the fuel pump prime at all. I drove around for 15-20 minutes with no problems, head back and park the car thinking the battery just needed a charge. I turn her off and then move the key back to II and the exact same thing repeats, except it didn't happen until I moved the key to II a second time. Headed back to class expecting to come out to a car that won't start but it starts and this time the problem doesn't repeat.

I need some help figuring out what this could be, I have classes until midnight and the last thing I need is to come out to a dead car in the frikken cold.

Main Relay going out on me or could the Ignition Switch be going bad?

 

Started the car up for the first time since yesterday and now I got a roaming idle from 600-1100, wtf is up with this car?

 

ive had random stuff like that happen. i didnt think it was the battery. sure as junk it was..just didnt have enough "juice" left. so id check the voltage of it.

 

checked my battery today.. supposed to be at 500 cca.. it was at 90

 

Alright I'll get the battery tested tomorrow and try cleaning the IACV. But I don't see how a battery could cause an idle issue or how my 2 problems could be linked unless it was something major.
