Even though I'm having some idle/driveability issues again with the ignition system, I'd like to take a second to brag about it. I drove it about 600 miles this past weekend, and it got me there and back comfortably. The miss appeared halfway through, but hopefully I'll have that fixed soon and it never ever came close to leaving me stranded or even having me worried.
Here's the AWESOME news: With the 3.42's and 35's, averaging 72 MPH, the first 210 mile leg of the trip I got 15.5 MPG! I stayed tucked in behind a tour bus the whole way lol and kept the TC locked, right around 1600-1700 RPM. Seeing as how this trucks life will mostly be long trips with the destinations being devoid of stop and go traffic, it was nice to see!
