I have a 92 prelude with a f22a6 (i know it could do a lot better
) and have recently found out that my car has more issues than I thought. I checked the codes and it came out with map sensor, exhaust gas recirc. (EGR), electronic air control, and,... speed sensor. I have been all over trying to find out more info on these problems. I was told to buy the Helm electrical guide to check if there was a common link between any of these codes. No one has it, not even helm apparently. If anyone has any pointers or ideas on things to check I would really appreciate it.
