Question -
92 Eldorado 4.9 liter
About 75% of the time I start out, the speedometer will not move. When this happens, the transmission will not shift either unless over 3500 rpm. Sometimes everything works perfect but that is only 25% of the time. The codes I am getting are:
E024, E052, E075 and E091.
Thank you in advance for any help you can give.
Answer -
OK, What you need to do now is to CLEAR all the codes and then re-enter into diagnostics and see which codes reappear.
Also identify which codes end with a letter "C" or "H".

AnswerE024 = VSS circuit problem.
E075 = intermittent VSS signal
You have a problem with either the:
PCM (computer)
VSS speed sensor
open ground circuit.
wire circuit shorted to ground.
