2002 S4 misfires and check engine light
Maybe three weeks ago my check engine light came on so I took it to Audi to get fixed. They hooked it up and said the computer showed it had a few misfires. I've noticed that it only misfired when it was cold and it literally happened maybe four times on random mornings.
So $500 later I left Audi with new spark plugs installed and my fuel injectors cleaned. (apparently they said there was some type of sludge in them). - I always run 93 octane gas so I'm not sure why that would happen - I've only had the car for about 5k miles so far.
On to my question, this morning on my ride to work while the oil was still cold I noticed that it was misfiring again. It never does it when the oil is warm only cold... and I baby the car when the oil is cold to prolong my turbos...
ANY IDEA WHY THIS IS HAPPENING BEFORE I TAKE IT TO AUDI AND DROP ANOTHER SUM OF MONEY ON SOMETHING THEY MIGHT NOT BE SURE ABOUT?
