so here's is probably a goofy question.i have a 1983 K10 with 383 stroker long bed with dual tanks, with less than. 100k miles. Why would I hear a significant change in My idle with my foot on the brake? I go from sitting there in neutral listening to my truck at idle, to pushing the brake pedal, and hearing the Idle pick up. Not crazy like redlining or anything but def noticeable to my ears. Is that a vacuum issue, because the master cylinder works off vacuum right?.
