Hello, I finally got a working ecu in my 91 turbo hatch with an OBD0 b16 swap and rc550 injectors. The car idles fine. When I hit the gas, it rumbles and shakes and sputteres and eventually revs up. It will rev fine very slowly, but the more you press the gas the worse it is. I just replaced the cap and rotor. Do anyone have any ideas on what could be the problem? Thanks alot.

 

youv checked the oil n all the fluids right?

 

Yes I just addes a little oil today.
