KA24DE high idle and not wanting to start

[asiandude15]

Alright, so first off my car was running absolutely fine a couple days ago before any of this stuff started happening. So, my car was absolutely fine and then I parked for like 5hrs a few days ago. I go to start it it doesn't want to start. I don't touch it till morning when the sun comes out and then I pop the hood and try to start the car to figure out the problem. Then to my surprise the car starts right up. A couple of days pass and about midday I go to turn my car on and then all the sudden the idle is incredibly high like 1300 to 1500. I literally can let go of the clutch completely in 1st gear and the car will move and not die! I'm like what the heck is going on, so I check my throttle cable and check to see if I have an air leak anywhere. Eveything checks out then I go and park the car. I come back about 1hr later try to start it. It turns on bit doesn't stay on for even 10 seconds and only goes to about 500 rpm and does. Then I crank it again and it doesn't want to start so I crank it and crank it for about 30 seconds to 1 minute an then it starts very roughly before high idle again. So, as of right now it's been doing this, I've had to crank it for about 30 seconds to 1 minute before the car starts roughly and idles high. Anyone have any ideas whats wrong? I've checked my throttle cable and no air leaks anywhere. The motor is bone stock!
