A few days ago I fixed an intermittent stalling issue with our 95 which was long overdue for some TLC. I found several vacuum hoses disconnected or perished. After I repaired/replaced those leaksthe car ran better than it ever has. For about a day. Then while out and about we left the engine idling for 5 minutes while we were out of the car and the engine had stopped when we returned Now it won't idle at all. Almost undriveable. The next morning when I started the car it blew a massive smokescreen out the exhaust. Any ideas/suggestions appreciated.
