Audi Repair: 2002 audi a4 1.8 turbo, throttle position sensor, mass airflow sensor

Question
when i accelarate the car kind of jumps or pulls back, a lot. when at high speeds it no longer does it. what would u suggest might be the problem? please respond as soon as possible. i greatly appreciate your response

Answer
This sounds like the throttle position sensor, or perhaps (less likely) the Mass Airflow sensor is not functioning correctly.  Is the fuel pressure OK, has the fuel filter been changed?  It may also be worth getting the computer codes read out.

Let me know,  Jan
