For a few months I've noticed that my Pioneer navigation unit was showing radically too-long trip times. Today I looked at a screen which shows that it thinks the vehicle speed is about one third the actual speed. It was running funny on a trip to LA earlier today, seeming as if the transmission was slipping. For a while, the AC was not blowing cold. I think all of this points to a computer problem. Has anyone else here had such problems? If so, what was the solution? I collect and restore old radios, mainly from the 1930s, for fun, and know electrolytic capacitors are not durable over the long run. Some newer flat screen TVs have been having electrolytic capacitor failures. I fixed one for a guy I was working with on a large abatement and demoliton project. Some guys on the old radio forum have also mentioned opening Ford computers and replacing bad electrolytic capacitors. However, before I try to take it apart, I thought to ask here, as it could be some other problem which is known to people here.
