I understand that swapping the computer is the "best" fix, but that implies that there are other fixes available. Moreover, is there an explanation as to why the check engine light does not immediately come back on when the same computer has been pulled out and returned to service some days later? Finally, what exactly is going on within the original computer which causes the check engine light to come on, and what is different about the new computer? Is this related to heat, age, milage, humidity? Why are cars in Jacksonville more prone to this problem?

Sorry for all of the questions, but inquiring minds want to know! Also, inquiring minds are loathe to spend $2000+ on a new computer. Thanks.
