HI, it's a 3.1tdi manual I have. This is an issue that has just started with no prior indications of any impending problem; It cranks over and won't start, but on the 3rd attempt, she fires up. The idle speed then goes up and down. When it dips, it sounds like it's going to stop, but then catches itself and continues to run, but then most times it cuts out when the revs dip. I pottered about with the fuel filter and retightened all the hose claps etc. With this, I managed to get her moving again, but when changing up to 2nd, the engine seems like it's being strangled of air or fuel? Then it cuts out and it's difficult to restart. Where is the best and cheapest place to begin the problem solving? Does this model have a fuel pump or sender in the fuel tank that could be causing this? Could it be a hole in the fuel line, if so would it be the feed or the return hose that might have the perforation? Could it be an external fuel pump issue? Does this model have an EGR valve than could be the issue? Or could it be an injector problem (God forbid!)?
Not sure where to begin the search with the best logical approach, your help would be most gratefully appreciated.
