Also you said it all happened around the time you cleaned your throttle body and replaced the throttle position sensor rite.Did this trow any check engine lights.Even if it didn't check for a dtc(You have to short your scs its a little blue 2 wire on the pass side and count the blinks).If you have never done this use the search button its all over this site.
