Default hr with rough idle

Hi, so my 07 had no prior issues but after going to the shop my idle has been f**** hangs at 500 for awhile (normal) then jumps to 600 and back to 500 drops to 400 ,350 then jumps to 1000 down to 600 and repeats...

slave and master cylinder went while I was on the highway, lost clutch pressure and couldn't switch gears.

So brought it to closest shop to get my slave and master cylinder replaced

I got my car and the clutch is super soft almost like if I'm driving a sedan. Before I used to have to kick my rpm before starting on first, now it just rolls into it with ease ....good?bad?

But also now I have a rough idle, what could be the problem?

took the car for a ride this morning...idle has gotten better stays at the 400 mark but still kinda shaky at times dmoving from 300 - 400.

other problems noticed when on the highway and i kick in the clutch i rpms drop and my car shuts off. inner city driving the rpms drop but not low enough for the car to shut off. also while in 5th and 6th gear i let the car glide and apply a small amount of pressure from time to time to keep me going , but now there is a jerk when i do this...when i apply more pressure this is not present , but i never had an issue prior.
My e brake used to be tight feeling like pressure working against and pretty much difficult to crank it all the way up... now its soft almost no pressure i can bring it all the way up with ease.

i brought my car to fix master and slave , but now im encountering all these other problems, car ran great prior to bringing it to the shop no

check for vacuum leaks.

I had idle issues when a hose connecting to the plenum had been moved just enough to cause small leak.

Sounds like you might just need to do an idle air relearn on the car. Also what are the intakes on your car stock?

sorry for the late response ...it was in fact a vacuum leak i popped open the hood the next day to check for leaks and they some how dismounted my silicone intakes from the intake box enough to throw off what the maf sensor thought the air volume was.

i mounted the hoses back on and it rides like a dream again.
