I have a 90 Cad Seville w/approximately 139,000 miles. I live in California and travel the freeway a total of 40 miles roundtip each day from home to work. My car has started backfiring and stalling out on me when I am stuck in traffic that isn't really moving. If I sit for approx.
30 minutes it will start up and I won't have any problems. This has happened numerous times and until a few days ago they couldn't find anything wrong with it. They found a code yesterday (E31, MAP circuit sensor fault) and replaced the manifold sensor. However, I'm told it's trial and error and they may need to replace my computer. Has anyone experiened this problem before? It's very frustrating especially when your call backfires and then stalls out of on the freeway. It still feels like it's missing when I drive it. Help. Thanks.- posted
