Try this:
Been there, done that. Try checking the fuel injectors (it is TBI isn't it?). One of mine died and set a code 44.
Code 44 is 02 lean, meaning not enough gas in the mixture. Likely a plugged or KIA fuel injector.

How do you manually clean an injector?

If it's just gummed up a few bottles of Chevron Techron in the gas tank might clear it up. If it's really fubar it'll need to be replaced.

I didn't know if there was a way to remove it and use throttle body cleaner to do it or not.

You could spray em' down real good with TB cleaner but that's not going to get the insides like a fuel additive will.
