My wife has a 2002 Outback, 4 cyl. with about 27K miles that she bought new. It has been a very good car and she loves it. For the past two thousand miles, the car has developed a serious power loss when accelerating normally from a traffic light. The engine acts as if it is rapidly being shut off and turned back on multiple times. This power loss is even more noticeable if accelerating from a stop and turning left at the same time. While the problem was intermittent at first, it is happening more and more often.
My wife says that once her speed reaches 40 mph or above, there is no power loss at all. She took the car to her Subaru dealer who hooked it up to their computer then drove it to test for the problem. They found nothing and noted on the work order that they had checked the A/F sensor and found it to be normal as did an inspection of the fuel filter.
Her concern is that this power loss could potentially be dangerous when turning a corner at a busy intersection, since her car loses power to the point of stalling. Anyone have any ideas? Thanks. -Paul
