same symptoms a year or so ago on my '88 80 Q, losing power, stalling never

>Help, please!  My Audi has an awful problem - it is intermittently losing
power, sometimes just

with power; and

with the so

lurching is as often as 3

I experience total

as if nothing is

mechanic has tried to

it may be a computer

anyone's suggestions

same problem.  Thank

>Heating unit for the car seats clicks when it has been on for a while.

dash push button will

>The car lurches when the A/C is engaged.
>There are 152,000 miles on the car and it has been very well maintained,
with only minor

years back.  Don't

helpful.
