| |
| | the engine has over 50,000 miles I would
|
| Hyundai Sonata GLS check engine light is
| |
| | say have your mechanic check to see if
|
| on and car sputters near my home. I take
| |
| | you need a tune up.If the engine
|
| it home and checked & was low on oil. I
| |
| | miss-fires (from needing a tune up) the
|
| take my husbands car to go buy oil and
| |
| | computer onboard will signal the yellow
|
| put it in. I tell my husband about it, he
| |
| | check engine light to come on to indicate
|
| takes it to nearby store no problems, no
| |
| | a problem has occured. I am assuming you
|
| check engine light.Friday I drive it as
| |
| | are talking about the yellow light not
|
| normal; probably about 30 to 50 miles for
| |
| | the RED engine light...correct?It is
|
| the day. No check engine light and no
| |
| | perfectly normal for the yellow light to
|
| problems.Saturday ran all day from here
| |
| | come and go if there is an intermittent
|
| to there no check engine light and no
| |
| | running condition, and low oil is usually
|
| problems, then I bring home the family
| |
| | not something that affects the YELLOW
|
| and go out to finish some shopping when
| |
| | light to come on. That yellow light is
|
| on my way home I think I hear sputter
| |
| | like an emission light, it is looking to
|
| again.Go to turn down radio at which time
| |
| | see if the engine is running at peak
|
| car sputters again, then jerks check
| |
| | efficiency, and not polluting the air
|
| engine light comes on again but I get it
| |
| | with too much exhaust from running
|
| home without incident after that. Decided
| |
| | poorly.When an engine miss-fires or
|
| would take it in after the holidays,
| |
| | "misses" one or more of the cylinders did
|
| moved it on Sunday from where it was
| |
| | NOT burn the fuel that was inside the
|
| parked started as normal. Husband said
