The usual problem is a corroded connector right at the throttle body. Try removing the square retaining clip and pull the connector off. Look inside and inspect for any green corrosion. Clean with contact/tuner cleaner and cycle the connector plug in and out of the fixed TB connector several times to sweep the contacts. Reconnect and try to start it. If it is not there, you got a wiring problem somewhere else; possible on one of the pins at the computer. A code 26 on that model is a high resistance or an open connection to the injector. Chrysler use to sell a replacement plug with a pigtail that you had to cut/solder on the wiring harness for the TB connector. I doubt it is available any more unless NAPA has it. Just try cleaning the connector first to see if it will start.Hi, helping my friend here with his 87 2.5l throttle body automatic lebaron. Its suddenly devloped a bad loss of power, hesitation and sometimes stalling issue. Only code is a 26, injector issue, wireing to injector was ruff so I replaced the wire, and rebuilt the TB with a new injector, no difference! Poped in a new good computer, no difference! Hooked up my computer to it and its mostly reading "lean", I put in another fuel pressure regulator and now its flicks to rich and lean but stays on lean longer and it ran well for the rest of the day! Next day it hardly would stay running and hardly moved with out stalling. I'm going to check the fuel pressure next, anyone have any other ideas??
