Thanks, lloyd and sfdon, my injectors have a blue top and the Bosch number is 0 280 150 003. I went back the the tread lloyd sent and the performance of 003 is very close to 043 on the performance chart. I was hoping I could blame the injectors for the horrible cold running performance and the poor gas mileage. As for the poor cold running performance, I removed and checked the auxiliary air regulator for function and tested temperature sensors and everything checked out fine. As for the poor gas mileage, I know I'm running rich, I can't get the CO under 4% and I can't adjust the idle speed at the throttle body. Once the car has warmed up however, it's running great.
