I have a 2011 3.0 6 cylinder Cadillac CTS AWD with 81500 miles that I bought used back in February. Up until two weeks ago I have had zero engine issues outside of on rare occasions when I would stop at a light it felt like the engine had a slight stutter, but nothing big.
Two weeks ago I went out on a cold morning to go to work and when I started the car it seemed different, like it wanted to die but continued to warm up as I backed out if my driveway I noticed the engine light blink a few times but then it went off. Car drove fine and no issues for two weeks. Then today I headed out to run some errands and car started and wasvwarming up just fine. Then a few minutes later as I was slowing down for a stop light it again briefly acted like it was going to die and again the engine light blinked a couple times but stopped. The light changed and I excellerated and no problems.
In both cases I went to AutoZone to have the codes scanned and there was no codes either time.
So what should I do or what might be the problems? I am also battling condensation in my passenger headlight, could that some how impact some electrical components of the Cadillac?
