Answer
Hello,

You did not specify the year or model of this Cadillac. I have no clue as to what your mechanic did. If done properly, he would have scanned the vehicle's computer system to see what faults caused the service engine and security lights to come on before doing any adjustments. My guess is that he reset the idle which just masks the real problems with the vehicle. You need to take the vehicle into a reputable repair shop that has the proper diagnostic scanners that will detect your problems. You don't have to go to a dealer. You can go to stores like Sears, Firestone, Good Year and others. They will be able to determine what exactly is wrong with the car.


Good Luck!
