Hi everyone. I finally joined because I recently purchased a car after moving back to the US after almost 10 years and had to sell my R34. Now It's a Blue '04 RX-8 I'll be enjoying in Hawaii. I've alre gained a lot of insight from this site and enjoyed the experience that was installing the BHR ignition earlier today.

I only have one question I'm hoping someone more experienced than I could answer and that I couldn't find previously on the site after searching.

My cars cruise control doesn't work when I first turn the car on. No lights on the dash or anything when I press the buttons. If I get up to operating temps and drive the car for maybe 30 minutes then turn it off and back on the cruise control works as it normally would. Is this some sort of electrical problem I need to be worried about? Could it signify some sort of underlying issue I need to get addressed quickly?

I have a CEL on but when I run the codes it's only for an O2 sensor that I'll be fixing when I get a new Cat.

Thanks for any insights you can provide and I look forward to posting more.

 

I had something a bit similar, but the cruise control was a symptom of a bigger problem. If it was cold, my ECU would throw a 610. ECU configuration error. If it threw the error, the cruise did not work. The fix ended up being a used ECU that I got rebuilt and flashed with the data from my old one when it was not cold. Circuit Board Medics did it, I did not go to the dealer.
