While downshifting I would rev my RPM and then shift and try to match the RPM with the gear I'm going into. But if I do if a couple times I will start to notice my idle dropping. Off the bat my idle sits around 1k (maybe a little under) and after doing it it drops down to about 400 - 500. Could this be a vacuum leak or something?
