my car recently started to have a rough idle and sometimes misfire while driving causing the car to jerk and the car has stalled on me a couple of times there is no check engine light on and i replaced to spark plugs and cleaned the throttle body. it doesn't do it all the time just sometimes and it seems to be worse when its raining.

 

what are the codes for the check engine light?

 

the check engine light is not on and i also noticed that there was a lot of oil in the throttle body when i went to clean it so i took it off and there was a puddle of oil behind it in the intake tube right behind the throttle body. i cleaned all of the oil out but it is still acting up it is the worse when its raining or the road is wet.
