Cadillac Repair: 95 eldo northstar service engine light., Ignition forensics expert, auto theft SIU investigation EUO denial expert

Question
service engine light on pressed off and up button on climate control fuel data center not responding with codes please help

Answer
Hello,

You have a hard code telling you something is wrong with the emission system and the vehicle needs to go to a service center (not Cadillac) to be diagnosed and repaired.

A soft code is one that can be reset or the check engine light goes out.

Driving like this will cost you gas mileage and performance because the computer is not in full loop.
