Default Car sputters at very low rpms. new to audis please help!

After the gear engages and i step on the gas (slighty or heavily), i get a sputter or lag. It feels like a knock but its not, more like im hitting a wall. (as if everything freezes for a split second) Then the rpms climb. The problem is not speed or temp sensative, and also occurs randomly (but getting more frequent.) hope i explained this well.
I am new to audis, but not new to cars. Unfortunately when i look under the hood it all looks so foriegn to me (no pun intended.) Ive been a jap owner my whole life so i guess you can see why all this stuff looks complicated to me. please help.

without a year, engine/engine code, and trans type... you're gonna get no information.

1.8T or 2.8? And my guess is either vacuum lines for the idle which is what my 2.8 did before i replaced them? Or possibly engine sludge. Which is typical on the 1.8's

the tach seems to be searching for comfort while idleing, rises about 200rpm then drops down agian.

Do a search for "throttle body alignment" and do that - it may help you out.

I recommend checking your gap on the spark plugs. Gap should be at .28

.028" only if the car is chipped. If it's stock the gap is .032".

it was two coil packs and two spark plugs on adjacent valves. didnt fix it myself but the price i paid is telling me different for the future. thanks for the replies guys. so odd to have a forum where people actually are willing to help you out so fast....never buying a jap car agian.
