I dont know if i am having the same problem but it sounds similar. Everytime when i first start my G and pull out to drive there is a weird squeak noise i hear. Sometimes at night when this happens it makes my headlight flicker when ever i hear that noise. I dont have any strange odors coming from the car though. Does anyone know what this could possibly be.

BTW sorry about hijacking your thread.

 

For some reason on my headlights, the lil ones on the side, one is yellow the other is blue wtf?

 

^ seems like your 04 with "like high mileage" was treated like **** by previous owner.
are you sure you didnt buy a worn down G driven by a ricer?
