2006 2.0 Check engine light, new battery won't fit ...
2006 Focus Z3, 2.0L. In the past 24 hours -- the check engine light came on, I figured it was time to change the factory battery after 4 years.
Went to W-Mart, the battery listed would not fit in the tray -- there is a boxed tab formed into the tray bottom that doesn't let the battery fit.
So, we reinstalled the factory battery and the check engine light is now off.
The W-Mart battery test said to replace the battery. My guess is that's the reason for the check engine light and that it will light up again, if I don't change the battery.
W-Mart did not list an air filter for a 2006 Focus 2.0L so I walked to P-Boys and their info said the car comes with a lifetime filter, and they did not list a replacement.
-- My open questions to fellow Fanatics: Is there an air filter to clean or replace?
-- If the check engine light does not come back on should I find a correctly sized battery and replace it after 4 years, or wait for it to die?
