    Have the code read either pick up a code reader or try a chain autoparts store sometimes they put the reader on for free. I wouldn't keep changing parts you may have all ready fixed the problem, but codes nee to be cleared after the repair to turn off the engine light.

    I have had my machinic check all possibilities. His answer was to go buy an code reader and turn it off when it comes on. I was worried about if I had a problem with my engine and he told me not to worry about it unless it comes on and is flashing. Bought a code reader from advance auto parts for 49.95 and now i can turn it of whenever I need to. I still worry about the light but don't know what else to do.
