I have a 89 dx corolla with a carborated 4 cylinder. The car only has 55,000 miles on it. Lately it has been missing here and there at all rpm ranges. I read the codes and 31 and 41 came up. I undid the connection to the carb and carb base and cleaned it with electrical cleaner and it seem to clear up for a day and then the miss came back. sometimes it chugs so hard the engine light stays on.
Any sugjestions would be appreciated.
