Sounds like you're on the right track. A bad TPS and ISC motor sensor
will cause the problems you're experiencing. Your ECM relies on the
readings it gets from the TPS to be sure there is enough air getting to
the engine. If the ECM gets a bad reading and thinks not enough air is
getting to the engine, it will cut the fuel supply, hence causing your
engine to die. Your ISC relies on the reading from the TPS as well.
It detects from the ECM if the throttle plate is closed or not. If
it thinks the throttle plate is fully closed, it will start allowing
air to enter the engine and bypass the throttle plate. If your ECM
starts seeing some unmeasured air coming from ISC and detects the
throttle plate is open (which it may not be due to a bad TPS reading),
the ECM will again cut the fuel supply to avoid the risk of detonation.
So, replace your TPS first and see if that cures your problem. Also,
check the resistence readings of your ISC to be sure that is within
spec. If your problem still occurs, check your Intake Air Temperature
(IAT) sensor in your air filter housing. Be sure your spark plugs,
plug wires, and distributor are all in good shape as well. Replace
your fuel filter if you haven't done so in the past 2-3 years.
Good luck!

when you hold the accelerator does the vehicle stay running? if so the problem is in ithe IAC idle air control motor, take a small screw driver and using the handle tap the iac motor and usualy the motor will kick in and the vehicle will run fine then if the problem is rectified replace the IAC
