My CE light came on last night on the way home and I checked the codes tonight via the normal procedure. I removed the cover and pulled the ECU out and took off the tape and turned the screw clockwise for two seconds then counterclockwise for two seconds, and the CE light started flashing codes. This was all fine and good except while I was expecting one or two codes, it threw up like 20 codes to the point where I ran out of space to write them down, is this normal? I know not everything throws a code that trips the CE light, but that many? And on 96 to 98 models the numbers are read like, 0401, which would be four long flashes and one short flash. Does a 99 model read this way also? How do I know what code tripped the CE light last night if there's so many?
