: rough idle, only when in gear and brake on

Hey you all! Just got ALL my other problems fixed. Now, I'm experiencing a rough idle when at a stop. It's one of those shakey types that are just annoying enough to make you want to fix.
The car runs smooth as silk when you're driving it.
Changed the PCV, and cleaned out the EGR. Plugs and wires are relatively new. The only code I'm pulling is PO-56 Trans-input speed sensor fault. Would this cause this idle problem? I'm skeptical right now, but let me know what you all think.

Thanks!!

Clean the TB. Mist the wires in the dark and see if they are leaking.

Thanks Ranger, almost forgot to check the most simple things first.. :banghead:
She probably needs a good scrubbin by the look of the air filter I pulled out last week.
What would you suggest: gumout or a careful acetone scrub?

Everyone says to use TB cleaner, NOT Gumout, but I still use it because I still have some. I suspect Acetone would work too. Don't forget the backside of the throttle plate as well as its perimeter.
