As an example, when my idle control valve was bad, the car misfired in all eight cylinders and had 9 fault codes stored (one for each cylinder + a multiple misfire code). No warnings, and this is with the latest stock software. You should be able to read any existing fault codes with your tuning cable
I see, thanks. Too bad I don't have a PC. I don't have the software either. I thought I heard someone say that the software is on the cable?!?!
