Looking for opinions and stories here. I know plenty of people have deleted them but I want to know how prone they are to failure. Seeing as how a 17 year old car that's infamous for electrical issues is my DD the idea that my ECU could say "Nope!" at any given moment and leave me stranded kinda worries me. So should I consider being preemptive and deleting it before something happens and be on the safe side or am I worrying for nothing? Thanks for the comments!
