[pen15]

hey all my problem is the gze im working on is giving me

code 2 and code 4 has anybody ever gotten these codes from a gze before and how did you fix it

motors background is hazy but was apparently running in the last car it was in so far i can not get spark and was wondering if its because of codes 2,4

the gze is from an 1988 aw11 afm gen1 4agze and 7rib non oil squirt if this info helps
