P0500 - Toyota Yaris Forums

I was driving my 2007 Yaris and notice the engine light pop up. The idle change it was riding a little rough almost like it wanted to shut off. The Transmission wouldn't want to go into fourth gear. The cruse control was also not working. I took it to the nearest auto zone and had them scan my car and the computer gave me a P0500 code. The speedometer works fine. Do you guys know where I should look? I've been looking at the repair manual and it talks to test the ECM but I was hoping someone else has ran into this situation before I start messing with that.
