When cold starting my 92 G20 after about 5 sec a loud noise will appear and last for about 10 minutes then completely go away. The engine will also Idle at around 1300-1500 for the duration of the noise. It seems to be coming from the passenger side mid to front. The power steering pump is new. I read some of the similar forums and the problems ranged from starter to alternator belt. wondering if anyone can help???
