Tries to stall ocassionally at idle but not always, display lights and airbag light flashes occasionally when just cruising down the road while it loses power and regains it
You have a power wire rubbing the chassis somewhere in the harness that when it slightly touches metal the voltage drops and causes the flickering and will make the computer act up. Finding exactly where the short is occurring will be a tedious and time consuming inspection of the wiring.
I was thinking that or the bcm because the doors will lock and unlock sometimes going down the road. What do you think about the bcm because I know it controls alot of this?
The BCM is probably being affected by the short too. Look at the wires inside the rubber cover for the doors.Check all the doors because any of them can cause a wire to chafe and short to the body. door

Pick up a copy of Haynes Diesel Engine Repair Manual, Part # 10330, at your local auto parts store. It has an excellent diagnostic section, check page 1-44. It's a must have for a diyer with a diesel motor. It costs about $20.

ok well try this when it stalls see if spark is present and if it is not and it cools down and starts then you might need to replace ignition control module good luck

First off I would suspect the fuel filter. You didn't state how long it runs before it stalls but I think it's not more than 10 minutes or so. It could also possibly be the Mass Air Flow sensor, but I really don't think that is it. If it was sputtering then I would check the Exhaust Gas Recirculating valve for clogging - a hands on diagnostic is really the best bet, unless you haven't changed the fuel filter in a while, in which case I would change that just for general measures and improved MPG. I recommend going to your local shop and have them clear the codes from the computer to see if the service light was just a glitch from changing the battery! If it comes back then you'll need to have the computer scanned to see what codes it's throwing out. Hope this helps!!

My 2006 Chevy Impala is doing this exact same thing. What did you do to fix it? Thanks
any time the check engine light is flashing the engine is miss firing, most likly cause is spark plug wires or colis, but also check the wiring harness from the crankshaft sensor to the ignation module they have a bad problem with coming out of the wiring lume and geting melted on the rear exhust manafold...good luck
