Soon after changing my coolant temp sensor my idle is higher than usual when the engine warms up. Checked for vacuum leaks, none. No codes. Tried to do a throttle body align but came back with an error instead of tb align. Any ideas? The tb is clean as well. It's a 1.8t. Thanks.

if my engine has been cold for a while it will always rev up a bit for about 30 seconds to a minute then go back down.
i'm pretty sure this is normal

I know, but this was happening when hot. I went to a measuring blocks view on vag-com and found the temp was reading 120c. That's way to hot. I pulled the temp sensor plug and found some pins that looked like they weren't making a good connection. Tweaked the pins with a dental tool and now it works great. Temp reads 85c on the computer now. Wierd!
