TobyMellin Posted June 29, 2016 Share Posted June 29, 2016 So after having my 2000 TD5 for a couple of months, I've noticed that at exactly 60mph, the engine becomes very lumpy and starts stuttering badly and the engine doesn't rev any higher. It feels as if it is hitting the rev limited but way too soon. My previous TD5 didn't suffer from anything like this. Does anyone have any ideas? Cheers in advance Toby 1 Quote Link to comment Share on other sites More sharing options...
Tanuki Posted June 29, 2016 Share Posted June 29, 2016 Is that 60 in 4th or 5th gear?? My 90TD5 goes up to 70 in 4th with no issues at all.... You may have a partly blocked fuel-filter that's causing fuel starvation; either the one under the rear wheelarch or the one on the end of the pickup-pipe in the fuel tank. (this second filter can get crudded up if you have slightly leaky injector-seals: combustion gases and carbon blow back into the tank and form 'black slime' with any condensation in the bottom of the tank, which then goos up the pickup-pipe and the in-tank fuel pump then burns itself out trying to draw fuel through the sludge). I'd change the wheelarch fuel-filter as a first step - and then if that doesnt fix it get an ECU fault-code reading done! Quote Link to comment Share on other sites More sharing options...
TobyMellin Posted June 29, 2016 Author Share Posted June 29, 2016 I'd have no chance of even touching 50mph in 4th gear before the stuttering starts. I'll change the filters and clean the lines out. I was unsure whether this was common or not. I'll plug it in tomorrow and see if anything comes back Quote Link to comment Share on other sites More sharing options...
Tanuki Posted June 29, 2016 Share Posted June 29, 2016 Also worth checking for oil in the injector-loom: pull the big orange plug off the under-seat ECU and check that it's all nice and clean in there. A 2000 TD5 could still have the original (leaky type) injector-harness fitted. Oil in the loom causes all sorts of odd syndromes (poor starting, misfires, cutting-out when idling).

TobyMellin Posted June 29, 2016 Author Share Posted June 29, 2016 One of the first things I did was change the injector loom and clean the ECU out so I know that bit is all good. I'll plug it in, change the filter and report back. Toby Quote Link to comment Share on other sites More sharing options...
Landrovernuts Posted June 29, 2016 Share Posted June 29, 2016 If doing the filter and checking fuel pump filter does not work try the filter in the regulator failing this test the fuel pressure. Should be 4 bar although everyone I have tested is giving a good 4.2 bar. Toby Quote Link to comment Share on other sites More sharing options...
dave88sw Posted June 29, 2016 Share Posted June 29, 2016 stuttering in my experience is usually a sticking wastegate. Quote Link to comment Share on other sites More sharing options...
TobyMellin Posted June 30, 2016 Author Share Posted June 30, 2016 The waste gate was partially seized. All sorted now. Thanks Toby Quote Link to comment Share on other sites More sharing options...
