This happened after a few minutes on the highway, sudden onset, really bad and consistent sputtering. Pulled off into parking lot, drove back, lasted about 10 minutes, even a blinking engine light for about 3 or 4 seconds (which disappeared afterward not to return). Then it...cleared up. I turned around again and went off to my destination, without those symptoms.
This seems like the first really bad instance of something that would come and go for a second or two, that I had later attributed to maybe bad gas. Then the so called 'bad gas' hitches, hesitation, lurching, happened after being put through one of the new-gen car washes. Something getting wet under the hood?
But then this happened a week later, this morning. Nothing ever like it--clean AutoScan last time--but this time an engine fault code, a misfire recorded for the very first time.
What is the most likely cause if I don't want to replace everything and just want to start at the most likely possibility? Coils? MAF sensor? O2 sensor? This is a really acute thing when it happens just for a second or two, however it happens only every few days or every week or so, and then it runs comparatively fine. But then, this, this morning. But after ten continuous minutes of this this morning, the car worked normally.
It did throw a brake light with wavy lines, all the way to my destination--but disappeared after restarting the car in the afternoon.
Best guess to begin with? Do I buy coils first?
AutoScan follows. thanks for any help, advice.
