Questionable start to my morning, but the rest of my day should be lovely

This morning when I was heading to work, in the darkness of ridiculous o'clock (6:45 a.m.), I had a bit of a scare.

There I was, making a left-hand turn on a non-arrow green. So, I mosey on into the intersection, as one should do.

Someone is directly infront of me, making their left-hand turn. They also mosey out. Unfortunately, their mosey blocked the lane of oncoming traffic right next to them out of my view. So, I go to turn, thinking all is clear ahead.

BUT NO.

There is a large car, coming right at me...so I put the ol' Galant into a mode that the poor thing has never had to go into, as I slam on the gas pedal. And I made it to my destination safely.

Now, for some reason...now my Service Engine light is coming on.

Hmm.
