Why do I have problems starting my 97 chevy astro when the weather gets very damp and humid? I'm sure it's an ignition problem. I smell unburnt gas, and after the weather changes, the car starts and after the flood of gas burns off it runs fine. this happens on a regular basis. Could an ignition component have a problem? I replaced the distributor cap and it made no difference.
