Hello everyone, I'm new at this so please forgive if not doing something right. I have a 1992 STS with only 60K miles, love the car but something strange happened today. The speedometer dropped to 0, everything electronic flatlined, and the transmission dropped out of overdrive. From a dead stop you have to manually shift the car otherwise it tries to starts in 3rd gear.
The following codes show all history, E052-I034-A050-I052 (for some reason nothing current, even though the check engine light was on during the time)
