I have a full manual so if any of these are familiar pm me.

what does your manual says about 71 EGR System Malfunction for a 95 ST auto. I have tried it all. I think my next move would be to change the ECU. that's the only thing I have left to do.

this is an excelent post and should be sticky'ed along with a link to that site the shows how to connect the terminals to check the code for people that arent sure. Art, I cant find it anywhere. I thought it was on celica tech but i dunno, I know you have it tho.

Thanks and the How-to articls explain the DLC connector. That is as long as you still have the cap for it.
