this is kinda off the subject but i am stumped, i have a 94 t bird and it is dumping gasand some oil into the exhuast. i just replaced the mass air flow sensor, and the engine has been missing i replaced the plugs ran the car then pulled all the spark plus out and the third cylinders plug had gas and oil on it. so that mad me think that the piston rings were bad. i did a compression test and its at 120 psi so know i dont think thats whats wrong, i am getting spark on that cylinder. does any one have any idea what could be causing this.

 

if your getting raw fuel into the exhaust then the pressure regulator could be suspect...no regulation to the injectors and a fuel build up does happen...zap!
