You can un plug the throttle switch to eliminate it as a possible problem.
You have a mixture or timing issue. Check the O2 and temp 2 sensors for
proper operation.

Subject: Won't accelerate

Hi to all,

I have this '86 van.  The engine runs fine, idles well but it won't
accelerate properly.  It wants to die.  Takes a few tries to have it
accelerate.
One thing I noticed, the idle switch is clicking off a little late, (the one
under the Throttle Valve)

I have no idea what causes it.
Anyone?
