Just wanted to say thank you to DJ for fixing my RCM. I got it back today in the mail and plugged it in. I turned the key and I could hear the fuel pump activate. The car started right up and NO MORE DASH WARNING LIGHTS! The spoiler button was no longer blinking so I was able to put the spoiler back down. I took the car for a test drive and the speedometer was working again. Everything seemed normal! I could be wrong but I think the car may have run better than before. It seemed very responsive to me when I hit the gas.

THANK YOU DJ and thank you to everyone for pointing me in the right direction. When I first started having trouble the RCM was the first thing that went through my mind. It turns out my first guess was the correct answer. It is amazing home something so small could cause such a big problem!
