I had numerous codes. found vacueum leaks and repaired. changed plugs and found one cracked, two loose ,and one that was burn a little more than the rest. My question is.. Two days after repair all was well. Then engine light comes on and gives me p0303 which i had before and went away.(cylender 3 misfire). What could be causing the misfire and which cylender is number 3??? Thanks for your help!!
I would say you were running rich and ruined one of the plugs. Just replace them all IMO
