Hey so I replaced the spark plugs yesterday , upon pulling 4 of the 6 plugs , I found oil soaked plugs.
I believe this is due to a leaky valve cover gasket , not something more severe .
I got the car all back together , and it starts right up and feels like it literally doubled in power , the only problem I am having is , in park , if I press the gas pedal even slightly , like 1/4 " , it literally falls on its face . ( similar to chopping the throttle on a dirt bike , )
the car idles fine and runs smoother at idle . And like I said doubled in engine performance . Except the falling on its face pressing gas pedal in park .
any ideas what it might be ?

I drove the car up the street and took it through the gears almost full throttle thinking maybe some oil that might of been sitting on the valve cover might of gotten in and was trying to burn it off and also trying to see how much of a difference it made just doing the plugs , which made a huge diff , it's only in park and when u first give it gas it'll fall on its face

Both , I'm pretty sure , prior to pulling the plug it would of just been on the top of the plug , only reason it showed up on the diode I believe is due to oil must've been puddled up by the threads , which leaked onto diode upon pulling
