Steve,

Thanks again for all your help. I check the info you pointeed me too and update on what I isolate for the P0340 code further.

Bob,
Ps; Yep the Red SHO says fast.... Have similar taste in workhorses as well. I have a 2000 F150 5.4. Put on a dual flowmaster a few weeks agao... Sounds great...
