Hi every body. I'm new here and am having some issues with my 09 fe 570. It just started idling bad. I figured out that it is super lean at idle runs fine above idle. It is not flashing any codes on fI light. sometimes for no reason it will idle just fine. Does anybody now what the fuel pressure at the injecter is? I was going to check that. Me and another guy check the voltage for all the sensors and they were right. I can't figure it out. any help would be great.
