problems...help

[adoodas]

SHIT...i got mad problems comin outta my ass all at once and it hurts. i got this weird loud sound comin from the main belt, i am losing antifreeze somewhere. there isnt a trace under the car, i got the head gasket and the intake pressure tested and it is sealed tight. WTF...why do i always get these mystery problems. i also got my check engine light comin on after 100km/h and it stays on till i shut off the car and restart it. i got it scanned at gm and they gave me an error code 77 which is the egr vavle. i read though on some other sites that a few ppl got the same problem and replaced the whole egr and it did absolutely nothing. also my high beams dont work properly, out of the ten times i pull the switch, it will work once, turn all the lights off 4 times(dangerous man), and do nothin the rest o the time.
what a bitch!
