low resolution pulse failure code 16 and quad driver module 1 fault code 26 its a 93 6spd transam ,keeps loosing spark ,cutting out anyone know what this could be ,opti maybe?

 

Could be the opti for the low res pulse but the quad driver module is the computer itself. It could be going out or just getting that code tripped because of the opti going out. I would try a ECM from a friends car first see if that helps if not it's the Opti causing the problem.

 

Agreed.

 

going by shbox.com,code 26 is either air pump relay circuit, egr solonoid, or evap solenoid is this correct?
