Hi.

I have a testpipe without secondary o2 sensor plugged in. It's just hanging for now. Yesterday I tried twisting it in the o2bung and the wires got real twisted and tight. Started car and CEL came on also my MPH tech is not working and now my car idles at 1100rpm. Went back home and unplugged the second o2 sensor. I have reset the ecu but car still idles at 1100rpm and mph tach doesnt work. This morning I backed up my car from the garage and the MPH tach went crazy from like 0-20mph and down back to 0. I have tried checking my cel and it only blinks one long followed by a quick short and then it keeps repeating itself. Does anyone have an idea what the hell is wrong with my car???
