Hi

I got all my coils and sparks changed last week due to a big and sudden misfiring problem which caused limp mode and engine light and all seemed to be good.

I drove for 170 miles some motorway and some back roads with a bit of "spirited driving". Then left the car over night. The next day driving down the motorway and after 180 since the new bits (10 miles that day) a subtle missfire reappeared under slight load then after about 2 miles it just dissapeared and drove for the next 110 miles perfectly fine.

any advice on what to do or what is wrong?
