Codes.....I just had all the spark plugs replaced in my 2003 Outback and the check engine light is still on and it is still running very rough. Any suggestions?
ez30D are very particular about what alternator goes on it. parts stores do not sell anything useful, except useful at giving repeat problems.Sorry to take so long to reply - had major computer problems at work.
The car has about 105K miles
Early in the summer I needed a new alternator (and battery), which worked for about 2 months and then stopped charging. The mech. said it tested good but I made him replace the alternator and it has been charging fine. Then the car started this rough running so the mechanic used his OBD and said 5 of 6 cylinders read bad so he replaced all of them. (I didn't see the codes).
I've had the car about 5 years with no mechanical problems and now engine problems. Have only done regular maintenance.
Does this help at all?
as opposed to a central coil, smarter coil on plugs on these,This is totally an unsubstantiated guess, but maybe coil pack?
H6 + rough running = coil pack has been my experience.
The CEL codes could help narrow it down.
