i have an 09 audio a4 3.2l recently the car needed a tune up because the car had a lot of vibration and shaking coming from the engine.
I changed a few parts.

All 6 spark plugs
All 6 ignition coils
both valve cover gaskets
fuel filter
and Map/MAF sensor.

That did not fixed the problem, now the car shakes a lot when im at a stop light the car doesnt seem like its going to die, But every time i try to fire it up in the morning sometimes it takes two times for it to turn on and most of those times i have to give it a little gas so it can turn on.
My mechanic checked for vaccum leaks but he couldnt figure out what was going on with the car.
before the car had about 7 to 9 codes on the computer. random mifire & Misfire on cylinder #2 #3 & #5.
Now from all those 9 codes theres only 1 or 2 left one which keeps saying malfunction on map sensor and misfire on cylinder #3.
Does anyone have any idea of what could be wrong with the car?
Any help would be much appreciate it.
Thanks!

 

I'm curious -did you get this problem resolve? I have an 09 audi a4 3.2 quattro as well and have been experiencing this for a couple of months. Took it to the dealer to clean the throttle body a little while ago. It helped a little. But now the "shake" is back. Just curious.
