Have had a lumpy idle at startup / smoke on my mk1 TD4 since I got it. It quickly levels out after a minute or so.
Recently changed the fuel filter and filled the new one with Kerosene to try to clean the system. After that ran through I put some diesel treatment in a Qtr tank of fuel and gave her a hard, high revving drive. On the way home from that journey, i lost power completely and it developed a misfire. No MIL. Starting it up after that was difficult with a lot of ringing required. It was starting on 3 cylinders.
While it was lumpily idling, I removed the injector electrical connections one by one. 3 of them caused the engine to die and one only caused the slightest change in engine note. I noticed that the nut on the fuel line to this injector wasnt actually very tight, so I tightened it and restarted. The engine started normally. Took it for a drive and it was fine, no power loss or misfire.
After an hour of uneventful driving today, it again developed a misfire......
I'm in two minds about whether my diesel treatments have caused something to dislodge and clog the injector or if this was limp mode brought on by something not liking my 4000prm spin the other day........ Im not getting an engine warning though.
Any thoughts?
