2003 pontiac bonneville idle issue
I have an 03 pontiac bonneville that i just bought and runs good down the highway but when I stop, it runs as if it is starving for fuel and sputtering really bad. Any suggestions?

First off, welcome.
Can you confirm what trim your car is? The GXP was not available in 2003. Do you have a 3800 in the car or a Northstar?

Glad to have another new member join us. Stalling, just a wild guess as you haven't posted if you plugged in a DTC reader for any DTC codes, fuel filter, fuel pressure regulator. It would help us help you if you could provide a little more information. - BC

I had that same exact problem. It was the EGR Valve.
