Car going lean when lights turn on
Posted: Mon Jun 06, 2022 9:14 pm
Hello, I have a b18c turbo that the afrs go lean when I turn on the lights. I have a clean injection fuel relay upgrade on a Walbro 255. My afr would jump 2-3 points. I’m on e85 and aus 1000cc injectors. I unplugged the light bulbs and then the afrs didn’t go clean but as long as the light is plugs in it would go lean when the lights are turned on.
