    6 coils, really?

    My 4 cylinder Forester had just one single ignition coil.

    I replaced it ($80) when chipmunks chewed up the wiring around it.
  • Yeah 6 coils. I just confirmed it today with the mechanic. Each cylinder had its own and one of them (coil for cylinder 2) burned up which in-turn blew a safety fuse that controlled cylinders 2,4 and 6. The car wouldnt start at all. I was told that the car needs at least 2 of the 4 cylinders to start. All said and done, its going to cost me $240 to replace the coil that burned up and to replace the fuse that blew. Im going to pick it up tomorrow. Ill let everyone know how it runs.

    More manufacturers are changing from a single coil and going to one for each plug. It eliminates the distributor and improves ignition performance.
  • since the 2008 tribeca has increased horsepower than the 2006-2007, can you change the ECM on the older units to a 2008 ECM and pick up the increased hp since it is using the 2008 fuel programming? :confuse:

    The engine is very different - it went from 3.0l to 3.6l, longer stroke, dog-leg piston shafts, etc. I'd guess it would not run at all.
