Default Idle issues... almost a pulse...Post Timing.

So, after I had my timing done last week I celebrated by having a 1000 mile weekend. The car ran great and got the best milage to date roughly 380 miles per tank(with ac). Now, when i am at idle the car feels like it is pulsing. The tach stays put at 800rpms but i now feel a pulsing vibration... 1 second on 1 second off. My guess is a vacuum leak... any insight?

thanks.

Default Could be misfires. VAG-COM to check for codes. Look at blocks 015 and 016. Also, I'd...

pressure test the intake to test for leaks.

Default Did you find anything on this? I noticed this same thing with my car earlier this week.

Thought it might have something to do with the A/C since it's the first time I've had it on since last fall.

Let me know.

TIA
