I have a `94 caddy deville concourse (32v northstar engine). She turns on but throws alot of white smoke from the mufflers. The spark plugs have a little bit of oil around `em. I think she might need new valve cover gaskets. Also, the pigtail wire from the gas pedal to the throttle body is kind of blocked and clicks everytime i turn the car on and off. I think it she might be accelerated. Could that have something to do with the smoke?
