I thought my ssv was causing power loss so I took it out and it was super gummed up. I made it nice and clean put it back in and no change. So after a few weeks I get p2070 ssv stuck open, now i know it's not the valve itself, plus it moves freely and cycles correctly. What could be? Actuator?

Could be the switch.....if it was damaged when you cleaned the valve especially. Did it get plugged back in? Could be the solenoid as well...but the odds of it deciding to crap out at the same time are low. I have seen the valve stick if it was installed a bit crooked as well...

 

Everything was fine when I put it back I was very careful. Before I cleaned it I had the same power loss and idle drops as I have now after cleaning it. And the cel came on after hard driving. I gave it a healthy run. Just yesterday, after a few weeks
