And also removed and cleaned my spark plugs. All these collectively seemed to have a great impact on the engine\u2019s performance! The engine runs much smoother and feels a lot more sporty!
New plugs and coils went in and the misfire is gone. Sounds healthy too.
41-156 is the new plug for the LE2 engine. Our 2016.5 got them, and they are fine. 41-123s came out of it.
Plugs need to be AC Delco 41993 (no substitution). I've had misfires with other "equivalent" plugs that went away with the correct plugs.
I did replace the spark plugs at 70k miles
Just changed out the original plugs in my 2014 Ed30 GLi at 58K and totally agree with the other observations here. The idling has improved tremendously and the general over all performance of the car is back where it should be.
Only use the factory AC-Delco 41-987 plugs.
Today I replaced the spark plugs with new ones PFR7S8EG VW genuine. With new plugs car runs better, but idle still wasn't good enough.
I have the same problem with my recently acquired 2011 Sharan. Tried a suggestion of new spark plugs with no success.
I initially got the P0101 code and did the obvious - replaced the MAF sensor. No change, same codes. Goodbye $100.
