i don't know much about escorts, except they are unavailable here.
I assume from your terminology its running a coil PACK.
If it keeps blowing them, then the problem lies between the computer and the coil packs.
Are ALL fuses of the correct grade? (not sure you would have one in this circuit, but ya never know.)
something is amiss, and i doubt its the coil packs. More like a wiring fault...job for a pro mate...unless you have a FACTORY manual, and KNOW what your looking for
