so its dumping fuel in the cylinders for no reason.


it has spark., hmmm, bro, this might be hard, is the check engine light on?/?

if it is, then somethings commanding the pcm to dump fuel in the cylinders like say you got a map sensor or a tps thats always at Wide open throttle.
or maybe an o2 thats shorted to lean commanding the pcm to dump more fuel.


if you got not check engine light, then check the vacuum line that goes to your pressure regulator and check it for wetness. If its wet, then replace the regulator.
