My brother and I changed out my spark plugs yesterday. The car idle weird before didn't burn or leak oil so we change the front no problems then we changed the back starting from left to right facing car transverse engine and when we got the one all the way to the right the coils was covered in oil. What does this mean? I'm getting 6-7 more avg. MPGS and there is no smoke coming out off exhaust. Also does the coil you take out have to go back in the one you removed it from, my brother can be a dumbass
