CEL on, doing something weird.
My 97 D90 has been doing something strange the last few days. It starts and idles fine, I'll let it run to warm up, but once I hit the gas it sputters and dies. Then starts right up and runs like it should. The CEL came on after this started happening giving a P0430(Catalyst Efficiency Low Fault bank B). I'm not sure what that means. Could this be the culprit?
