Answer
Hi Matt,
From that description it sounds like you have a K-car LeBaron Executive sedan with the 2.6L Mitsubishi engine. That engine is carbureted and has a feedback circuit but the engine controller has no self-diagnostic capability. I have personally never seen or worked on that engine though I have the manual about it for '85.
I do know of a fellow owner who has lots of experience with that engine who I believe would be able to give you some direction on how to solve your problem. His name is Willam Vose and he participates in the Yahoo autos group titled: The Chrysler LeBaron Club. I have his email address it is:
wmvose@cox.net

P.S.: I wrote to Bill and here is his response:
"I would bet on a catalytic converter issue. The 2.6L has two, one in the exhaust manifold and one undercar. The exhaust manifold one can and will break up and clog the exhaust pipe. The other issue with the 85 is the feedback system is a POS on those due to the Mitsubishi electronics. I will be glad to assist him if I can.
Bill"

So mention my name to him when you write, and please give him as much description of your engine's behavior so that he will have something to go by.
Please let me know if you need some more help on your car. I just know very little about the details of that engine compared to Bill Vose. I might be able to help with other aspects of the car.
