Firebird Formula 350 Running Rough
 

Hi
I have a Firebird Formula 350. It is running rough (doesn't want to idle well and stalls occasionally). The exhaust fumes are very rich and it is using heaps of fuel. I have recently replaced the IAC Valve. I have also replaced the spark plugs, leads, new oil and filter, new coolant had the valve stem seals replaced and am not sure what else it could be. If someone has encountered a similar problem I would love to hear from you.
Thanks
Adam

Hey, I've got a '90 350, and I had the exact same problem with mine as well a little while ago. When idling, (especially in rush hour traffic) it would stall out on me. I found out that 2 of my fuel injectors were clogged and not enough fuel was getting through which was causing the off idling and stalling. Hope this helps you out, good luck.
