oxygen sensor. all the things you mentioned really have nothing to do w/ the check engine light coming on. replace your oxygen sensor and it will go off.

Unhook your NEGATIVE battery for no less than 30 seconds to completely clear the code history in your ECU. It is important that you disconnect your negative cable first and reconnect it last any time the battery is unhooked. If you disconnect the positive first, it causes power spikes which can damage the ECU.

the o2 sensor may be the problem also the tps(throttle position sensor) may be causing it
