Pretty Bad Problem
On my 99' A4 2.8 Q when I start it up I have to depress the accelerator to even get it to start. When it is started and idling, when I push the gas it hits this snag at about 1500 rpm where it misfires occasionally (meaning about every third time). When it does this, it shoots out dark(er) smoke out the exhaust. It seems as if it is choking for gas the entire time.
Anyone have any idea what the problem could be??
