Hello,
My wife was driving the car the other evening (after we just got back from a 250 mile round trip) and the "check engine" light came on. The car still drove perfectly and started fine. I took it to Autozone yesterday to pull the engine codes, they hooked the scanner up and they kept getting a "link failed" message... I ended up clearing the code(s) by disconnecting and reconnecting the battery and the code(s) have not reappeared.
The vehicle is the v6 model and I just replaced the fuel regulator, spark plugs (Bosch Platinum +2)- along with the intake manifold gasget, and changed oil/filter last week. It has 60k miles on it now... any ideas? thanks
