Hello:
As some of you are aware, I deliver newspapers nightly (or morningly) from approx. 3:00AM to 6:30AM, with approximately 2 hours of that time spent driving with a lot of idling. Well, on rainy / misty / moist days, on my final approach to my home and climbing a 5% grade hill (of perhaps a half mile at most) and at almost the exact 2 hour running mark my engine starts to sputter like you wouldn't believe; disengaging the clutch seems to help a little bit, but even when I do that the engine will often just stop running. It runs so rough that it seems like the engine (with clutch engaged) acts like it's going to jump out of the engine compartment. Today, I added a container of gas cleaner immediately, but the problem arose again when I continued past my home to run another errand and had to climb another gentle grade. After sitting for a half-hour or so afterwards, the truck ran fine. I won't be able to get this looked at for a few weeks. Has anyone ever run into this before? This only happened one time on a non-rainy day, and oddly enough that was 2 1/2 hours into a return trip from my brother's in CT (and as I climbed a gentle grade at highway speeds). I'm stumped.
Thanks for all of your past and future help,
