Engine sputter/idle rpm surge.

Post by the draggin » Wed Aug 10, 2016 5:59 pm

My 1998 1500SE has what was an intermittent idle surge and it seems to sputter as if it is missing but it seems to be a fuel issue not an ignition problem. I have a manual for a 1988 but I'm not seeing how to balance the carbs or to troubleshoot this issue. All the articles I have found and videos I have watched do not cover 1500 wings or they are on the 1988 units. I could really use some info on the 1998 models. The intermittent sputter seems to be constant now. I've run to Seafoam mixes through with no improvement. The engine runs great out on the road but when you get into stop and go traffic it starts its sputtering and the exhaust smells terrible.

Classic symptoms of a lean running engine and likely due to carb problems/vacuum leak issues.
