My communications skills seem to be as weak as my digital/electronic
diagnostic skills...
These two episodes occurred, both, at the end of a sustained highway
run...the first following a short pause to open a gate and then getting
back on the throttle to climb our driveway in my second gear...this
driveway climb normally takes maybe 1/3 throttle and I go up this rather
steep pitch at about 3500 rpms and maybe 10-15 mph.
The second instance happened after a 60mph run of 50 miles, then a right
turn 90-degree turn off onto a smaller access road, followed by what is
normally an acceleration back up to 4th or 5th gear. .some drivers reach
full speed along this two lane paved section, I normally just go back to
about 40mph or so along this 1/4 mile access road.
Both times as I resumed speed, that was when I encountered bucking and
stumbling...both times, upon nursing my vehicle along to it's destination,
short distances only, I shut off the motor. After a bit...first time it
was overnight, second time perhaps 15 minutes, the motor started right up
normally and ran just fine...after the first episode and my superficial
diagnostic wire-wiggling and contact cleaning, I did the second trip of 50
miles and had the second episode of stumbling. I drove another 50 miles
after the second episode without any further misbehavior from the engine.
That is where I am now.. Time to fix this...
So I could say these problems occurred during sustained highway driving,
yes, in that the motor was never shut off. I just took my foot off the
gas to turn the one time and stopped to open the gate the other time.
During both these trips I did have terrain that called for sustained 'no
throttle' running, substantial downhill sections..One of these, I often
coast with the van in neutral as it is a couple of miles long, downwind and
just the right pitch to allow the van to remain at about 65mph without any
help from the motor...but this road is up and down, climbing and dropping a
bit...not flat. I negotiate the whole thing at about 60 in 5th gear
except coming west when I climb that one section (the one I can coast down
at 65) ..There are some frequent sections where full throttle is called for
to maintain my cruising speeds...
