car has been running really well...decided to change oil -5w30--penzoil platinum and mobil filter- backed up out of garage and parked in idle and had misfire...took about 1.5 weeks of driving and finally got a P0302...replaced plug and swapped coil to 4 and still have this issue...but only when in D standstill or in park...if I throw in neutral...smooth...if im above 15 mph , perfect ...just low idle...any ideas??? TB are clean, MAF is clean..PCV too...

 

Unsure however I see a trace.

P0302 is Misfire cyl #2
Cyl #2 is driver's side first cylinder
oil cap is closest to this cylinder
In my history I have spilled oil during changes.
In my history I've seen how oil tracks towards #2 coil

I suggest you take some soap/degreaser to the connector, pull #2 and #4 and disassemble the coil from the boot and clean the boot really well.
Possible that oil fell inside of the hole as well.
With the vehicle on pull the connectors and see which one offers no change.
Pull the sparkplug and should be wet with a bit of fuel.
Double check your PCV and Breather pipes as well.

 

thank you sir! yep...drove it around neighborhood and misfires got worse and then at the last moment of pulling in driveway, steady engine light...read it and p0304, so yes, this can definitely be it...!!!!! will check this weekend and see much appreciated Bull
