Yea the vibration in low rpm's is the awd, i also had a tsi-awd and bad suspesion combined with AWD will cause that. As far as the sluggish and the bad gas miles i'm not sure. I know that when i bought my car it ran like #### then i replaced the plugs AND wires and it was fine. I suggest replacing the wires also. Another thing that i have heard is the MAP sensors on these cars are know to break. That may attribute to it since a bad reading could change the amount of fuel being added.

 

anybody know how much a new map sensor is?

 

i replaced mine and i think it was around 100. Its just a very small part that goes on top to the intake manifold.

 

BTW you should be able to get it at any parts store (autozone, ect.)

 

Taking off in to low of a rpm will do that.. So if you take off with to low of a rpm with a fwd it would shake too... You just need to take off at a little higher rpm..

 

well right now im not so much concerned with the taking off and rattling thing, its the 8 effing miles per gallon that has got me pissed off right now.

 

Yea i had my car for 2-1/2 years and i never fixed the rattling thing. Most of that problem comes from the suspension.

 

ive had a 4wd car before and i KNOW it shouldnt act this horribly until halfway up the rpm meter. Something is wrong and i know it.

 

oh yeah, also after i put the new plugs in and drove around for a while i took one back out and it was covered in dry dark grey carbon type stuff.....The car sat for 2 years before i bought it. Could it just be all gunked up or something?

 

I'm not sure if this woul have anything related but i would read it and see if it helps

The part on detonation. Once again not sure, just a hunch.
