wondering if i'm crazy...
this is going to sound a little weird, so bear with me. i have an 87gl
westy. recently, i cleaned the motor and transmission exteriors with
gunk engine brite and a power spray (local spray and wash). this is
something i have done a number of times, with no ill effect
(electrically, and etc.). well, after the last wash, i noticed that the
van is....well...hypersensitive to that moment between acceleration and
deceleration at around 3000 rpm. that is to say, cruising down the road,
at around 3000 rpm, if i take my foot off the gas, there is a noticable
jerk as the van goes from forward torque to reverse torque. when i give
it gas again (same rpm) there is another noticable jerk as the van goes
from reverse to forward torque. at low speeds (1st gear) when this
occurs, the jerk takes on whiplash like proportions. the van didn't used
to do this. the jerk is not accompanied by any clunking, or differential
noise, and the van otherwise runs perfectly (a relative term). the van
shifts smoothly, and i can move through the gears from 1st to 4th with
no problems...the problem surfaces only when i'm "coasting", alternately
pushing and releasing the gas pedal to maintain speed, and again, its
worse around 3000rpm. i realize that a certain amount of this "jerking"
thing that i'm trying to describe is perfectly natural, and i have begun
to wonder if it's all in my head, but after driving it around town
tonight, i'm convinced that the van is driving differently than normal.
that the "natural" jerk has been somehow amplified.
i'm wondering if, as a result of the power spray, i've lost some sort of
electrical connection, fouled some solonoid, or some other such thing
that would explain this behavior. before you ask, i did check the
electrical connections on the distributor, and checked the inside of cap
for moisture. no moisture, and, while the wiring harness (which is
attached to the distributor) is showing some wear, everything seems
intact (and my guess is the van wouldn't run at all if this wasn't the
case). my gut instincts tell me that this is somehow an electrical
problem (distributor, sensor faulty wiring, etc), not a mechanical
one-but i'm open to any suggestions. this is one of those things that i
can learn to "drive around" but ...well, its difficult to describe how
profoundly irritating these little gremlins can be. if anybody can help,
it's someone here on the list.
