Need to step on the gas to start the car when it's been sitting for a few hours.
When my car has been sitting for few (approximately 4)
hours or over night it requires me stepping on the gas
petal, in order for it to start. It does not require this if it
has only been sitting a little bit (under 4hrs.) Then it starts
just fine. I thought maybe the battery was going out - so I
replaced it. This did not help. I took it to the mechanic
and the only thing they could find was the throttle plates
had some carbon buildup which they cleaned. He said
this would help and it really hasn't. The car has 123,000
miles, I purchased it back in November from an Audi
dealership at 118,000 miles. I would say this problem has
been there at least since mid December.
I'm not sure what could be causing this issue. Is there
something specific, that I should have the mechanic be
checking in order to solve this issue?
