1991 Lebaron Convertable Code 26

When I first start my car it runs fine. But once I shut it off an
restart it the check engine light is on and it runs ragged. It neve
fails to start and it keeps running, just runs terrible. The cod
reader is giving us a code 26. We have done all the recomende
fixes(cleaning connection and changed oxygen sensor) and it still run
terrible. We would appreciate any ideas anyone has on this problem. M
husband is a mechanic but not up on all this computer stuff. Thank

 

Your '91 LeBaron has which engine?

Code 26 indicates high resistance in the injector circuit. Could be
dirty/corroded injector connectors, dirt/corrosion at the 60-pin plug on
the engine control module (SBEC), or faulty injectors.

Your husband is "a mechanic but not up on all this computer stuff"? What
does he work on, then? Computer-controlled automobile engines have been on
US roads since 1969, and in universal use for around two decades.
