I have a 95 st and it is now running very rough and misfiring. it won't go about 3000rpm as the ecu cuts the fuel. I have a check engine light, but when I short the e1 and te1 pins nothing happens. Is there another way to get the code?

do you turn the key to the on position when you do this?
Te to e1 is what you are supposed to jumper, so it should be working for you -------------------- 2001 Celica GT-S Turbo

Maybe she'll give it up after dinner and a movie?
Try TE2 and E1. TE2 is the advanced diagnostic port. |

At least the ones in Cali don't do it no more. I don't know about other states and stores. This post has been edited by ILoveMySilly97: Dec 18, 2012 - 3:15 PM -------------------- |

I figured I would post and update in case this happens to anyone else. After replacing my ecu the car runs great. No CEL and no misfiring nothing.
So long story short, if your pre96 celica throws a CEL and you can't retrieve it and all the sensor and voltages check out at the ecu, then it's time to replace the ecu. |
