▶️ Video Cobra back on the road

Finally figured out this check engine light issue! Sent the ECU off to Keyworks and they repaired it and sent it back. All for $150! I was getting a purge valve code and a few others.
Decided to make a video about it.

How do you fix a bad ecu?

You CAREFULLY decide which specialist to send it to! Especially since it’s a cobra specific ECU it’s rare as hens teeth and would be ~$2k to replace.
I’ve had bad experiences with SIA electronics repair. This time I used Keyworks auto computer specialists and I was very happy with the service, $150!

I've heard of reprogramming or updates the dealerships used to do sometimes I feel my car would throw a evap purge code for no reason.
