Like I said before, the front O2 sensor is important. Without a signal from that, it's just going to dump fuel at idle.

the o2 sensor fixed it now it runs great other then when you go to start it you have to keep cranking it for it to start which may be the fuel pump ive change my fuel filter already

If you don't have a fuel pressure gauge you can normally rent them from auto parts stores. There is a test fitting on the end of the fuel rail towards the passenger side of the vehicle. Let it sit for a day or however long you're able to and check the pressure, and also check it while cranking. You may need a friend or to set up a camera for that. If you don't have any leaks and the fuel pump is healthy, it should be able to hold pressure for a number of weeks or even months. Normally a failing fuel pump will back drain and lose pressure quickly. It's been a while since I dealt with a stock pump but you should be seeing at least 40psi. Anything lower may indicate a failing pump or leaky lines.

Also another easier check is to turn the switch from "OFF" to "ACC" a few times, leaving it at "ACC" for a second or so each time. That will prime the fuel pump and restore fuel pressure, allowing an easier start if the pressure were draining/leaking.

You know much about the A/C system because I put freon in my car and it was cold for like a day or so then it went back to warm? I checked the freon level and it showed it in the red, so I let some of it come out to go back in the green and I think that's what messed it up.

Now with A/C on or off it makes this sound and still doesn't blow cold I'm thinking I messed up the compressor but I really don't know.
