I just finished installing new spark plugs and coils, started the car and let it run....everything ran smooth and idled fine.
This morning on my way to gas station, the check engine light came on and then I noticed the speedometer didn't work.

Did I forget to plug something in?

Also when I started up the car the power light flashed 16 times and this never happens..I didn't unplug the transmission resistor when I removed the battery.

I didn't check the code yet until I get home later today.

Has this happened to anyone before?
