I have had the same problem. I changed fuel filter, added fuel injector cleaner, still runs rough as hell at a idle. Didnt think it could be the fuel pump, because ran ok at hiway speeds, it only stalled when giving less gas, not more. So in theory I figured couldn't be fuel pump. I was so wrong. At hiway speeds you have inertia, engine is running faster already etc. Its the fuel pump. 90% of the time in GM cars thats what it is when it behaves this way.
to change the fuel pump:
In the tank, the following is a run down of how to replace it..
This is actualy a pretty involved repair. You have to have the car jacked up on all 4 corners, or up on a car lift. Disconnected battery, and it is recomended you have as much gas as posible drained from the tank. Then underneath the car you will find the tank with 2 staps holding it in place. Those staps should be taken off or at least out of the way while the tank is being supported. There are vacume lines, the fuel fill and vent lines, and the wiring harness that all have to be unhooked. Once you are sure that all lines are disconnected, drop the tank and pull to the side. Wash the top of the tank off, there will be dirt and rocks on top of it, and you need to get all of these out of the way. You will see where the wiring harness goes into the fuel sending unit. Around that peice is a slide ring that has to be gently hammered counter clockwise. Once it is free from its retaining clips, the fuel sending unit will have to be wiggled out very carefully. Once out, you will see the fuel pump mounted in line on the fuel sending unit. You will have to work out how its mounted in line, and get it off and unplugged. Reinstall the new fuel pump and reverse the procedure.
Lock ring O-ring
Posibly the fuel sending unit if you were having problems with your gas gauge.
Hope this helps!

I had a similar problem with my Saab, stalled at red lights when idling,
As suggested by Greg I suspected the IAC and was just about going to the repair shop and have the ECU codes pulled.
Anyway, I decided it could be a good idea to check the engine air filter first. It turned out to be rather dirty so I changed it, This solved the problem in my case, the car has worked perfectly ever since.
Sometimes it can be very simple!

Just make sure that the outlet on the fuel filter is pointing toward's the front or to injector's. There is no air to be bleed out of fuel system, just turn key and fuel system will pressureize, also check your fuel cut off switch might be located at driver side kick panel, will have a round cover with fuel shut off on it. good luck, hope this was helpful.

Standard Answer for Timing Belts/Chains: 100,000 to 120,000 miles is when the Timing Belts/Chains start malfunctioning or failing. Some people want to go ahead and change them before malfunctions/failures happen.
I just replaced mine on 2002 Dodge Grand Caravan which just turned 100K. Most Timing Belt/Chain failures will cause more costly engine damage when these fail, including a need to replace/rebuild an entire engine.
Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!
