90 tracker hesitates when accelerating

[fixkick]

90 , ever set the VR gap, or it can be a bad dizzy.
this car has stand alone dizzy, makes all its own spark.
i an extra vacuum line to cab and to a propane tank
if if it misfires, i add propane, if it clear up, it was lean if no change bad spark,.

hesitates or bogs.
bogs then catched up. or deep endless bog
hesitates, is this mifire? you can feel it, does it misfire? or just bog.
if its gross misfire, id bet the dizzy is bad, (tune it up and set the VR gap)
if it catches up. that bog, then the TPS is bad.

the TPS ,cause (bad) a bog, for 1 or 2 seconds, then catches, up.
called a TIP IN bog. The bog is corrected when the naturally slow map sensor wakes up (see reality) the added propane at bog will make it better.
the TPS is hard to test, they get old
the carbon ring inside wears out. and fails to send the signal to cause TIP IN enrich mode.
find out if its spark or fuel
then work that.
it can be hard to do that. (add fuel is one trick)
