I'm looking for a local (DFW) mechanic who knows the 4.0 in and out. One that could listen to a 4.0 from 20ft away and tell you exactly what the problem is.
I'm mechanically inclined but new to the 4.0. I think the lower end is a little loud but could just be the way they always are. So I've got some questions..
Any help would be much appreciated!
