Hey how are you guys doing, i had a concern with my car i just rebuilt my motor and got it running but once i finished installing the rest of my parts and went to fire up the car i ran into a misfire issue so i checked my spark plugs and wire and they were pretty beat up so i got new ones and the misfire didn't go away. once the throttle is held open the car will run but once it closes the car will mis and stall out i was wondering what could be the cause of this. i also took out the spark plugs and found come type of liquid on my cylinder 1 and 3 pistons the liquid looks like it could be either fuel or oil more on the clear side.
