So, im having an issue where i would come to a stop and im on the brakes. Roughly about 10 Seconds later... engine starts to get a bit rough. I began to think its something to do with the brake booster or a vacuum leak since it only happens after braking. Took it to dealer and they said it was normal, but it didnt used to do that before. Any idea of what else it could be.?

 

Welcome to the forum,
I too would suspect vacuum leak or poor recovery....

 

sounds like booster valve is not shutting properly

 

Didn't think about that one, but I will try and see if I can take a look at it and see whats up. If I can manage to get a smoke tester to check to see if there is any small leaks somewhere because, apparently in an a compartment on the drivers side of the engine bay behind the headlight, there is rat poop... so it could be possible that it got chewed into a little bit which is causing the leak.

 

they're having issues with the engine mounts, some need shimmed or played around with but the complaint is usually just rough idle has nothing to do with the brakes
