On the Subaru Outback 3.0 / 6 cylinder engine there is a problem with
the computer aided ignition system and carborator. My car has 40,000
miles on it, but it has been happening since around 30,000 miles.
On long trips driving at 60- 65 miles per hour for longer than an hour
the engine starts to hesitate and jerk. When you slow down the car
wants to run on and stay at the faster speed. It takes heavy brake
application to get the car to stop. After finally stopping the idle
speed greatly reduces down to slower than normal and will sometimes
stall. After stopping and resuming normal slower speed driving, the
engine immediately speeds up. Inorder to keep from running at a faster
speed then you would desire, you must apply the brakes. While this is
occuring when the automatic shift tries to move from 1st to 2nd and
from 2nd to 3rd the shifting operation is a violant kick. Making me
think the transmission has been dropped off of the drive train. Driving
the car in gear in this mode is like a jerking go then hold motion.
So I was able to drive to the dealership and they said it is the
sensors that periodically take a statistical "snapshot" of the
carborator, throttle plate, fuel richness, etc. These sensors are out
of adjustment and need to be replaced. The dealership said this
problem has been happening a lot on the 3.0 / 6 cylinder engine because
of excess carbon build up. Cleaning the carbon build up will only
temporarily fix the problem. This check engine light / carborator /
iginition system problem never happens on any of the 4 cylinder
engines. And yes, if the car is driven in this condition for long
there would be serious problems happening to the drive train.
My car is under warranty and Subaru USA picks up the tab. Anyone out
there with similar problems?
