2002 Camry 4cyl P0401

I replaced the vacum switch valve 25860-0H020 and reset the CEL. After I replaced it the engine ran fine at idle in park but in gear very rough vibrating the dash. I thought the computer my have to adjust, a few days later the idle is better but still idles pretty rough in gear and the CEL is back on. I double checked all the hoses and installation did not find anything obvious.
I looked at the other post on the 01 maybe I bought the wrong part is the vacum swith valve the same as the vacum solenoid valve?


Thanks for everyones help!
