My 84 50th turbo, 5 spd will not run at idle, and runs rough when I keep the rpms at 2500 or over, at operating temp. runs great when cold. I am not throwing any codes, it has a new cat, o2 sensor, chts/cts, the egr is working and has new tubes, and I have swapped the ecu. Idol/air, tps seem to be ok too. It has 139K on it and has good compression, doesn't use oil, doesn't over heat, and doesn't leak. What am I missing? I have read discussions about similar problems here, but so far, not much resolution. Any help is appreciated. I'm in CA, so I have to live with the smog *****.

This car reminds me of an old Yamaha Virago motorcycle I had. Seemed that people loved them, but at the same time, everyone had major issues with them and had to invest a bunch of time just to keep them running.
