hey guys i have been working on my fto for weeks now and i have problems still when the car is at idle it revs between 500-1000 rpm and sputtering sounds like its running on 3 cylinders but when u rev it high say 5000-6000 it sounds much better like the injectors are being drowned in fuel so i got the car idling again and took off the front electrical connections to the injectors and although the engine wont run on all cylinders it was so much better in both sound and idling was much more smother
any suggestions i going to change the ecu as i did an engine swap but didn't change that
