haveing problems with a 88 vet shutting off going down the road, any help please

 

The possibilities here are many! Why don't you try a search on here and see if you can narrow it down some. You can start changing parts,ECM,fuel pump,distributor,coils,on and on. I recall there being several other folks with very similar problems recently so the help is there! Good Luck!

You need to first determine whether you are losing fuel or fire. Fuel could be fuel pressure, injector pulse, spark could be coil, module, ESC (Electronic Spark Control). As you can see, possibilities are numerous.
