1988 Astro Van. Engine rebuilt, over 7 years ago, quality job. Never had
any real problems other than the peripheral things one would expect to
encounter. Alternator, water pump, etc. Lately, however, the engine is cold
starting. It starts, and you have to let it warm up really good, before
attempting to put it in gear or go anywhere. It will definitely die if it's
not warmed up. Lots of engine stuttering.
We just did an extensive trip (2000 miles in a week) and along with the cold
start problems, we noticed a sluggishness in the cruise control. The cruise
is an aftermarket installation (installed many years ago), but once again,
has been flawless. On this trip, maintaining constant speed on hills was a
struggle. It seemed ok, if you "helped" the cruise with the accelerator
just a bit. Also, not when cruising, but when accelerating to pass another
vehicle, that the kickdown was sluggish.
My mileage on trips has always been 20 or 21. On this trip, my gas mileage
was down to 19 and 20.
The engine is sound, doesn't burn, leak or use oil. Compression is good, and
it doesn't run hot. Transmission was rebuilt about 50K ago.
