1997 Integra. Auto. Driving home on Monday, car started missing really bad. Then the CEL popped up. Pulled over. Checked to make sure all the plug wires were secure. Had a paper clip, so I jumped it. Solid CEL. Didn't blink, didn't go off, just stayed lit. Looked at the codes list and assume that it is Code 0 - ECU. I nursed it home as I was almost there. So question, I'm in the process of resetting the ECU as we speak. Is this a wasted effort? Is the ECU toast? Could anything besides a fried ECU throw this code (that I'm assuming is zero)? Or should I just go get a new ECU?
