I’ve had a vacuum leak from the breather hose off of the intake not being hooked up. Fixed it because I was running lean. Now I’m running rich downstream fuel system 1. And now currently running lean on fuel system 1/1. Unplugged each coil at a time to see if motor would change in idle. All of that was fine. My fuel injectors are pretty consistent with each other. My IAC current reads at 4286.50mA. Is that too high? And also my EGR flow reads 0 even at 2500rpm. Has anybody had this problem and were able to get fixed? Or any body have any ideas?
