剛在autozone上查了。是這樣寫的：

“Check Engine Light On
If light comes on while driving or remains on, your vehicle may have an
emissions or sensor problem and should be analyzed. If light flashes, the
condition is more severe and must be checked immediately to prevent
catalytic converter damage. ”
看來我的是前一種情況。這個問題修一下大約得花多少銀子啊？保養時沒查出這種問題
正常嗎？
