Hi
i have had my a 93 TBi astro off the road for nearly 6 months now

so far what has been replaced:
new distributor whole unit including cap, rotor arm

Do you have any codes? Have you checked the timing? Could it be the PCM? How many miles are on this vehicle?

PCM is power train control module, in other words the computer!
I have a 93 Safari with 205,000 miles on it. It is more dependable then my 2000 Astro!
