86 gxl secondary injectors fail!
with my secondary injectors plugged in it sputters very bad between 4k to 6k and wont rev past 6k. but when i unplug them it revs fine. i pulled the injectors out and tested them and they seem to work fine. what could be causing it to run terrible with them plugged in?

Check your grounds. http://www.aaroncake.net/rx-7/grounding.htm
Check your pressure/boost sensor.
Finally, have all 4 injectors professionally cleaned by an injection shop.

i have added the ground to the pressure sensor and installed fresh wire through the harness and under the intake for the ecu ground. now it runs pretty good until i get to 5k under a load and it sputters and wont go past 5k??
