White plug is a lean mixture, that and the high idle would seem to indicate an air leak in the intake.

the part that confuses me is how is it pure burning gas out the back and then lean at the plugs.... does that not contradict each other or is that just becuz i have no CAT.....

i first thought of an air leak i think i will take like wd40 and pray around the throttle body and check for any change.....

thanks guys

Pure gas coming out the back? like dripping?
or could this be water, sure it's not coolant?
that creates white smoke too, and would do
funny things to the plugs as well as drip out
the tail pipe.
