but did you spray it with carb cleaner all around it to make sure it doesnt have a vacuum leak..does the idle change??

Yes, I did use carb cleaner. However, I found one of the loose hose, and that has fixed the problem I think. I will drive around to see if that has fixed the problem.

P0401 code popped up again. I don't see any loose hoses. Any ideas? Could it be upstream oxygen sensor?
