6.5L MAP issue

Thank you all, again, for your helpful advice. It turns out that the two issues were a break in the wiring on the harness & a perished map sensor seal. She's up & running again!

6.5L MAP issue

6.5 pros and cons

After Old blue (in my prof pic) was destroyed in an unfortunate head-on collision, I started my search for another GMT400. I, too, went for the 6.5L search too. I work in the fire service & we had a support vehicle with the Detroit in it that lasted over 500k w/just a PMD relocate & general...
