3.0l mpv 92 started sputtering but always recovered until it died in town. No spark-plugs good, cap looks good as well as rotor. Junk yard found 93 coil igniter combo-still no spark. No spark at coil. Tried different combinations of both coil to igniters. NG. Could the computer be an issue or both igniter coil combos be bad? Pickups in distributer possibly. Fuses good. I'm at a loss. Ran well until sputtering problem started month ago. Check engine light has been on for a while-never checked it cause it was running good. Any help out there appreciated. BTW-dealer price for igniter coil is 469.00 plus tax!!!! Thanx
