also, its 2 codes now
ignition cyl 4
misfire cyl 4

haallppppp!!!

Use some non flammable BrakeKleen by CRC and compressed air - down the spark plug hole. That should get rid of any old oil residue.

So... new VC ad VCG. What spark plugs? Dealer bought ones? IF not that would be my next step. Then IF you have good spark plugs it will be time for new injectors and/or carbon cleaning.

So this is odd. I wanted to see if one of my new coils was faulty so I swapped #3 and #4. Now no errors or rough idles. Does that make sense? I was expecting a misfire in #3 if it was a bad coil or stay in 4 with the oily plug. A little confused. 3 hours of driving so far and no issues... Yet
