Hey guys my old man has a 2000 model 4.2 wagon, and he's been having problems with it lately. We recently went on a trip to our farm out at stanthorpe, and it was fine on the way there all good and driving around all the very hilly country all low range work. Not a problem, but on the way home I started missing and coughing and it wouldn't rev above 2500 rpm, so if you changed back down a gear to go up a hill it wouldn't rev at all. So we pulled over changed the fuel filter. Off we went was ok for a bit but still doing it. But problem and basically gone. We went put there again the weekend just gone, and the thing started doing it again. So we changed the filter again got about 1 I'm out of warrick and it was still doing it. Pulled over checked all the fuel lines, they were all good, but there this one like little filter looking thing, which Nissan call a control valve just after the tank. We took that off blew it out with the compresser little bit of shit come out but not really much. But it's still doing it, he's ordered a new one of those control valves, ($95) for a tinny little plastic thing from Nissan. I was just wondering if anyone else had any ideas to try, or if anyone else has had a problem with that part?
Any help would be great its gotta be something simple. regards Jesse
