Acceleration issues
 

Hi guys maybe someone can help with my 1998 audi A6 Quattro . I have replaced all my spark plugs, my wires, crankshaft pos sensor, even my cam pos sensor. My car still wont accelerate at all. It forces it self to get to 1000 rpm then after that its perfectly time but when i put it in any gear the car wont accelerate at all the car and it will even shut off. Now my check engine like is on and flashing i have changed everything it has gave me. But it keeps telling me. Random multiple misfire and cyclinder misfire 1,2, and 3. Can someone please help me with this issue.
