Thanks for all of the help! I turned the TRAC off and I the LOW did not flash yesterday. I think it was just a coincidence that it happened before the problems with the MAF the last time. So.... so far, no problem at all and the car is running fine. My car is a 2000 and like I said in my post the last part they got, was the correct GM part - by Delco- I do believe. So, most likely the first two they put in were for the 97-98, that makes more sense than 2 of them going bad.
I am on day 11 and no problems as of yet! Thank you, I will keep you posted and used some of your tips if I do have a problem. I really appreciate the time you both took to write to me, Betsy
