I had the Check Engine light go off on the car.
O'Reilly Auto Parts pulled the code, and it was a Thermostat ($30). Most shops wanted $200 for the repair (including parts), but YouTube made it look like I could do it myself.
It's estimated to take a professional mechanic 1.5 hours, it took me 4 hours. Yeah! I did it.
I didn't even kick and scream and yell once. I did loose a tool in the engine area... but I stayed calm, and got it out, and continued.
Celebrating the small wins tonight.
