My cel comes on when i first start my car, after the engin warms up. if i shut the car off, then restart it, the cel stays off and wont come on again no matter how many key off and key ons i do. will do it again once the engine cools down. i pulled the carpet back and exposed the ecm. took it down and searched for my test lead...I DONT HAVE ONE! i traced wire loom up into the dash and still, no test lead for the OBD1 system. ill post pics gto prove this if needed, but even with cel on, the car runs fine....i HATE seeing a cel...any ideas? oh, and this is my first post since joining the site

 

Wait, so youre saying yo dont have the jumper to get the code for the cel?
