I have a 2002 subaru forester with 104,000 miles
8/22/12 I had the thermostat, timing belt, and water pump
recently replace valve cover gaskets, spark plugs, oil change regularly
when I am driving around town the thermostat runs just fine
when I get up to highway speeds my thermostat drops to Cold
it only started to do this when the temperature dropped here in denver
its been in the 20s and 30s i dont think that would have too much to do with it
the check engine light came on when it did this last night and i had the code checked on my way to work
its saying
1- A/F ratio is off
2- Ignition malfunction
3- Catalytic converter failure
the car is running strong and smooth not noticing anything wrong
all fluids are at proper levels
would this be a faulty alternator?
im stumped, anyone have any suggestions on where i should start?
any suggestions would be much appreciated
