Volvo D13, 2012 Fuel Stumbling, is it injectors pump or fuel system?
Ok people lets see what y'all can come up with.
Engine seems to stumble as if it was fuel related. Had injectors tested and it passed a response test and a bubble test. It is driving me crazy(and broke) looking for a fix. It doesn't do it all the time is the problem. Sometimes it's like a sewing machine and sometimes it's like taking a spark plug wire off grannies nova. Today it started out running slightly rough then poof, ran perfect for 600+ miles. And it's like this most days. It clears up within the first 50-100 miles or it stays like it all day. And then tonight it did something funny as well. I stopped in at the Petro and had a meal and shower when I called it quits. And I come back out and it took 6-8 seconds to start up, something that has never happened before in it's 583k miles. So if anyone has some ideas please help.
Is this a worthwhile discussion?
