I've got a 1995 stratus ES with aa 2.5 V6. When I start it up for the first time in the morning, it tends to stall when I back out of the drive way. after it warms up it tends to run fine and not stall. There are no codes, the dealer told me to change the EGR valve, I did that and no change. What could be going on? After it stalls I can usually start it right back up but a couple of times I had to try several times to get it started. Any advice would be greatly appreciated. Thanks.
