I have a '97 Outback 5-speed with about 96,000 miles. The car runs
great but during the past week or so it has developed a strange
"thump" sound when I start and stop the engine. The thump occurs at
the end of the starting cycle and also when the engine is shut off. It
is there 80% of the time, not 100%. Anyone have experience with this?
First I thought that something was loose, but now I believe the engine
computer may be sending an ignition signal at the wrong time.
