inchman Posted October 21, 2014 Share Posted October 21, 2014 hi all strange one this, while driving home at the weekend i noticed my 90 ( 300tdi auto) wasnt idiling the best and hunting when at a constant rev. i changed the fuel filter when i got home, no difference, in fact seemed to be getting worse no power at all and when held at a constant rev gradually died out. i had a new lift pump in the drawer so i fitted it no difference, checked the quality of the fuel supply lines, the main line to the lift pump wouldnt hold a vacuum, i thought thats me sorted. changed the fuel line from tank to lift pump all good, started it up and still the same, revs for a minute or 2 the gradually dies out when being held at a constant rev, has anybody any ideas, before i pull the injection pump for a service, cheers gary Quote Link to comment Share on other sites More sharing options...
Jode Posted October 21, 2014 Share Posted October 21, 2014 1. Did you drain the sedimentor (if one's fit - I think they were standard for the deffer 300 tdi)? 2. Injectors given a clean recently? 3. You may have a split in the LDA diaghram. 4. But if it's hunting I'd suspect a split in the air cleaner hose. Quote Link to comment Share on other sites More sharing options...
