Not that i recall but I’ve been fighting it for a while now and feel like I’ve chased every possible common issue with no change

Yes i have done this also. There is plenty of vacuum. No leaks anywhere, fluid or vacuum

My 2013 sport has had an idle issue since purchased (used) dealership related it to the cats which were replaced. The issue seemed to be a bit better and i figured after a few miles it would clear up, now 2 years later i have still not determined the issue. Both cats, throttle body, injectors, spark plugs and idle control valve have all been replaced with no change in idle. Vehicle only has the issue when in drive and stopped like at a red light. It’s more of a vibration/idle issue when the transmission is in gear. Could it be a trans issue? Am i looking in the wrong direction???

So issues all began with my wife parking on a steep street at a friends bridal shower. She calls saying her pedal is super stiff, after she arrived home i took it for a test drive and confirmed the stiff pedal that you had to stand on the get vehicle to stop. I consider myself pretty mechanical and after checking the obvious thing I determined that the master had more than likely failed. After replacing the master, then booster, replacing all brake fluid, bleeding each tire with a compressed air bleeder and purging the ABS module with a scan tool the brakes are now super soft pedaled and don’t work great unless you hit the brake pedal quickly like your stomping on them. Did i get a bad master or what am i forgetting? I have also tried the slamming on the brakes method to trigger the ABS and nothing has changed. Please help a guy out!
