When I start to accelerate slowly my car stumbles and sometimes dies. But this happens inconsistently and already had my car checked and replaced a lot of parts.
New: sparkplugs, high tension wires, fuel pump, fuel filter, oil, atf, atf filter, ignition coil, condenser, and lastly topoverhaul. The car is draining all my money. What should I do?

Stop throwing parts at it, you generally will not find the right one and if you do, is was by chance.

First, are there any error codes, If not then find a shop that has a scanner compatable with an OBDI 1994. Scan the ECM in live data for any errant readings.

This could be TPS, EGR, CAT, O2, or possibly the ignition module.

Thank you sir for the quick reply. BTW, when I cleaned the distributor especially the Ignition Coil the problem stopped for almost a month but then came back so I assumed that it was really time to change the coil but then after 2 weeks the problem came back again.
