Hi. I changed the OEM injectors for 4x720 injectors and the rtek 1.8. Now, when I start the car the idle is unstable and the Afr also, the mix is arround 10.5-11.5(video).After this I changed the 720cc injectors for the OEM injectors. The car started to work better but the mixture at the idle was the same that the one obtained with the 720cc injectors: 10.5-11.5AFR. The ECU is running with the OEM O2 sensor, I dont have the Wideband connect to the ECU. Any one can help me?Thanks in advance
