Hi guys, I need your help urgently, a few weeks ago my 95 eldorado had problems with the solenoid valves of the tranny and also I had the P023 code while the car was sometimes hesitating. With the information of the technical archive I was able to replace the solenoid valves, now the transmission runs perfect. The other problem P023 is still there, I already changed the sparks, the spark plugs, the wires and the ignition modul with the coils but the car is still hesitating sometimes and the SES light appears, when I check the trouble codes P023 current appears. Can anyone help me. Thanks for all replies wwhich are helpful. Franz
