To invoke the computer relearn cycle on a 1993 Chrysler New Yorker Fifth, first, disconnect the negative battery cable for about 10 minutes to reset the engine control module (ECM). Reconnect the battery, then start the engine and allow it to idle for approximately 10 minutes without any load, which helps the ECM recalibrate. Afterward, take the vehicle for a short drive, varying speeds and engine loads to complete the relearn process. This should help the ECM adjust to new sensor readings and optimize engine performance.
