Now... I think I got this right... the green connector is under the dash, right by the ECU. But, is the white connector under the hood, by the firewall?? Or is there another connector under the dash that I'm forgetting? The CAS code (16) was coming on, it was gone for a few days, now its back?! And the EGR code (35) was on ever since I acquired the car, but its gone? CEL turns on seemingly whenever it feels like it... oh and it's a 1986 fuel-injected GL.

86 was theonly year spfi connectors are under the dash (and iac tube to the air box)

 

anyway the white(or black connectors should be immediately there next to the green connectors

I'll go outside and take a look for another set of connectors.

 

But then whats the pair of white connectors by the firewall? (like where the greens are on say... an '88 DL)

 

Thanks Miles!

No other connectors under the dash... just the green one and a white one under the hood...

 

When nothing's connected, it brings up code 16 and 11. (Crank Angle Sensor and Ignition Pulse)

 

When the green's connected, it brings up code 16 and 35. (Crank Angle Sensor and EGR)

 

When the white's connected, it shows no codes, nor any CEL with the key in the ON position.

 

When both are connected, it brings up code 12, and the CEL flashes.

 

I've done a heckuva lot of searching on this forum, and havent found anyone with my case (mainly the CAS code) and still have the car running. It does idle odd, but thats about it. Plus, the engine is making a ticking/knocking noise, but thats a whole different battle, I believe. I've timed it with a light, at 20 degrees with the greens connected, replaced damn near all of the ignition system (excluding the big expensive parts) and it still idles funny, and these codes keep coming up. Funny thing is, when I'm driving for like 10 minutes, the CEL turns off for a bit, then comes back on and wont go off again....

 

Am I the only one with this kind of problem or something?!
