Re: Vacuum Hose and Vacuum Testing
Gents, I have a very similar problem, although I was certain my lumpy running was down to the vacuum hose. The vacuum hose was split, rubbers had perished, and I cannot purchase a new one, as I live in Abu Dhabi - the Ford dealer here is pretty useless. They cannot supply a new hose assmebly, so I repaired the hose myself.
Problem is, when I first repaired it, it ran fine. Then the hose split again further down after a few weeks, so I repaired it again myself. Since I repaired it again, it is now still running a little lumpy, and if I accelerate hard, the service engine light flashes. Once I take my foot off the pedal, the light dissapears after a few seconds. Is there any chance a piece of perished hose could have been sucked down the vacuum hose and caused a partial blockage somewhere, causing the lumpy running? Or am I looking in the wrong area for a fix?
