ok, ive searched the site. didnt see exactly what my car is doing. it leans out at the above rpm, and when the peddal goes from cruse to wot. if i had a carb i say the accelorator pump wasnt working for the wot thing. ive fixed some problems, secondary injectors wer bad and the little black box that reads vaccume that is mounted on the passenger side strutt tower. any ideas??? im new to the efi, so i need some help here! the car is an early 87 gxl.

 

my thoughts: secondaries... ditch them, or clean them by remvoing them, not just injector cleaners.
just my .02. ppl please help.... limited knowledge here... since i work on one not more than 6 months.
