My 95 Z71 starts fine and runs perfectly through out most of my travels. From time to time when I come to a stop at a stop sign, or light, it stumbles runs really rough the SES light comes on, and it stalls. It always restarts with a variable amount of trouble. It continues to chug and sputter until I get back into motion. The next time I come to a stop, it may or may not do the same thing. I can't tie it to a certain operating temperature, or condition If I drive 50 miles on the freeway, it may or may not do thesame crazy thing when I stop at the end of the ramp.
It's a 350 V8 with about 140 Thousand miles. The only odd circumstance I can think of is, I let it sit for about 10 days while family member was in the hospital a couple of weeks ago, and it just hasn't been right since.
Any advice would be greatly appreciated.
