Code 12?
I pulled the check engine light codes, and got code 14 at first, then it threw code 12 twice, it never threw 14 again... 12 is a Knock Control Sensor Signal code from what i've read... 14 is an ignition signal...

I think when I was researching this on my 87 4r, code 12 is rpm signal. Which could be the knock sensor. But all my searching led to finding out very rarely does the knock sensor itself go bad. Its most likely a conection from the sensor to the ECU. check the pig tail. the sensor itself is on the passenger's side under the oild filter I believe.
