The check engine light... It's the bane of my existence, and it never seems to be finished toying with me. We have a 2001 Toyota Corolla (the one that needed the engine work mentioned on my dad's blog, and for the most part it's a great little car. However, we've been fighting with the check engine light for a long time, and no one is really sure how to fix the problem.
The light itself isn't really problematic. The car still runs just fine and gets us around without a problem. Unfortunately, when the light is on, the car goes into a "safe mode," where the engine computer won't allow the engine to run efficiently. Translation: gas mileage dropped from high 30's/low 40's down to low 20's. And it won't pass emissions inspections.
Fortunately, it's only been somewhat of a problem lately. After the major engine surgery, the light and I have had an "on again, off again" relationship (bahahaha). Before we left to California, the light had been off for some time (after a couple of ons and offs). On our way back to the hotel from the beach, though, it came back on. Normally it turns itself back off after a hundred miles or so. This time it didn't turn off for the whole 642 miles home from Disneyland. We were starting to get worried.
Prayers were answered, however. Just earlier this week the light turned off again. Life is good.
(And the mileage wasn't affected much on our drive--we were still pushing low to mid 30 mpgs going fast with AC blazing).
