Btw, I'm not sure if you're aware but cleaning the solenoids is just blowing shop air threw them.
UPDATE: Well i have driven to work now 3 times with no light. I also have checked for error codes after getting home each night and got nothing. I am continuing to monitor.
By the way the code I was getting was the 2A99 code. It was the only code showing up.
