Default WTF Headlights????

I'm dying try to figure out what I've done. Symptoms are the check engine light is always so I though I have a poor engine running issue. Car has a little stumble until it it runs for a few minutes and then runs great. I thought the stumble was causing the check engine light. Only code it had was code 33. I cleaned Mass Iar flow and replaced intake air valve in throttle body. Light still on!
Daughter takes car for drive and uses headlights. The car starts beeping like the engine is off with the headlights on. Now im thinking it is all electrical caising the check engine light and head lights.
Yup, ive have been in the steering column replace pins, blinker and cam, key assembly and the tiny plastic item for turning key to start position (go e thru 2 of tem now).
How do I trouble shoot my problem:
. check engine light stays on constantly
. The car beeps/dings like the car is off when usi g headlights even though it isnt.
