Question: Hi, I have
Audi a4 1998 2.8 v6 30v quattro and it's manual. my car starts jerking at 1500 rpm and the rpm slows down and it
always lacks power. when I drive I have to press the gas pedal all the way to
the floor to make the
car start to move. I changed the gas filter already but that
didn't help. I went to this one place where they checked my computer and the
code told me that there is a "throttle position malfunction" problem and also
the check engine light is on and sometimes the car starts jerking while it's
idling and the check engine light flashes. also I have to start my car a couple
of times to make it idle by itself. another thing is that I have to be in 5th
gear to drive normally on the highway. please respond as soon as possible
Answer:
Sounds like you need to replace the
throttle position sensor or check it's wiring, connection, and function.
