Liquidhorse,
It sounds like you know what you're doing and have the right attitude to troubleshoot the problem rather than just changing parts. Like you, all I have is a $100 code reader. You're actually one up on me with that Android app you downloaded. Good luck!;)

Wendymccann,
Thanks for the update! It's good to hear that you found the problem.:D Unfortunately, that fix didn't work for me.:(
