My 240 with lh 2.2 has really rough idle and runs rich at idle. I have replaced all the injector seals and fuel pressure regulator. Did a complete tune up wires plugs. Cleaned the throttle body. Checked the flame trap. The issue is getting worse over time. I did find a leaking injector seal but after replacing and testing the issue is still there.

The exhaust really smells to. Im kind of at a loss. Any help would be appreciated.
