For what it's worth... I thought my ECU was bad. It was throwing some random codes, but I could hear/feel it misfiring which wasn't what the codes were saying. The dealer said I needed a new one and priced me $1600. I had them reset it instead and it's been fine since.

 

Well, my left strut kinda went bad, so anytime I hit bumps, it's pretty rough and noisy. The shop thinks it was just too much impact repeatedly, an eventually ruined a circuit board inside the ecu. It drives fine sometimes, but then certain bumps will just cause it to stall.
