Thanks for the advice. I looked at two used Superduties today. One nice 07 350 with 55K miles, exactly like my 06. Salesman offered me 10,000 for my truck and wanted 21,000 more. I just can't believe his truck is worth three times what mine is! I did not want it anyway, as I found it had been lifted and had big Mickey Thompson 35" tires on the 20" rims. Drove like crap. In my opinion, he screwed his truck up. I just dont see lifting a long bed 350 crew cab. It's not a truck I would want to go trail riding in.

The other had also been all tricked out with aftermarker parts. it was funny when the salesman drove it over to me, he squealed the tires accidentally. Again, if I wanted a sports car, I would buy a Porsche, not a Superduty.

So my second opinion dealer shop agreed # 7 injector was toast, and said one other on the other side was weak (strangely a different one from the first opinion) So I am going to just have the two replaced. I just don't put many miles on it (about 8,000 a year) so hopefully the others will hold up. I felt more comfortable with this dealer, as they did not seem to be running up the tab.
