Another newbie here.
I bought my wife a 2003 SE model with a little over 100k miles on it. I found this site by googling ford focus forum. This was the first site in the search. The reason I came here is because her car is surging at various times. I found a great article on cleaning the IAC, and I am hoping that will fix the problem.
Anywho, great to be here. It looks like it is a very informative site. Yall have a great day.
