Matt, I have an 88 GL, and when I first got it had problems similar to yours.

From my experience with my machine, I recommend that you begin by getting the
idle speed set properly for starters. If it is not on the button, then the other
components of the system witll cause wierd things to happen.

Warm the engine thoroughly, disconnect the ISV, shut the enginge down then
restart. Adjust the big slot headded screw on the throttle body until the idle
is about 900 rpm (works best on mine). Then shut down, reconnect the ISV, and
crank 'er up again. If all. components are in good working order, it should
perform well.

Some shade-tree dude had tried to adjust my idle, and didn't know squat about
it. Got everything out of whack, just by turning that throttle body screw
without disconnecting stuff. Gotta do it. Try it, you will be surprised.

Good Luck,
