Car Forum / Subaru Cars / January 20092001 Subaru H6 intermittant engine missing on the freeway
I have a 2001 LL Bean H6 with about 120K miles. I have had a fe incidents of the engine sputtering, missing, cutting out like th ignition is quitting. All were on the highway after many hours driving The first time after a while I crammed the throttle to the floor whil going up a hill and it went a way. I hoped it was just some bad fuel. I happened again on a couple of other trips but the full throttle tric didn't make it go away. It just seemed to come and go. Always on long trip. Unnerving when a couple of hundred miles from home. Neve seems to do it around town. No CELs and I ran a diagnostic with my cod reader and nothing stored. Anyone have an idea like maybe an ignitio amplifier over heating -- skiki Message Origin: TRAVEL.co > I have a 2001 LL Bean H6 with about 120K miles.

Anyone have an idea like maybe an ignition > amplifier over heating? hmmmm....I'd expect you would at least have a 'generic' misfire code stored. weird. Maybe an inspection of the plugs would help pin things down to a specific cylinder or something? I dunno - if it would ever do that while idling or throw a code, much easier to track down.

Anyone have an idea like maybe an ignition > amplifier over heating? Hi, In the dark, open the hood and see if you can see sparks fly around along each plug wire. Next I'd inspect plugs. I install Iridium plugs. They last long time. "only after many hours of driving" suggests everything under the hood becomes heatsoaked. I would suspect the coil pack. > I have a 2001 LL Bean H6 with about 120K miles.

Hi - I've had exactly the same problem - usually after a long run on a motorway (UK) - it's as if the engine just 'dies' but after a momement of panic (in the fast lane at 70mph) and slowing down it just seems to right itself as if nothing has happened! And then everythings fine for another 1000 miles! Weird - and NOT good. Never happened with my 1999 2.5 Legacy ..... |
