1994 Dodge Caravan Q&A

1994 Dodge Caravan Question: What would cause my 1994 Dodge Caravan to run extremely rough?

My 1994 dodge caravan started to misfire, idle low, have an extreme smell of gas come from it, aa well as blow blue smoke. The engine actually vibrates quite a bit when running. When I looked at and cleaned the fuel injectors the engine all of a sudden started to idle extremely high. What would cause this as well? The problem first started to occur once in awhile when it rained and then it corrected itself. 5 days ago it rained really hard and ever since then has not corrected itself and has gotten worse. -
