Hello everyone,
Completely new user on the forum here, first post, also a relatively new owner of a 90 Td5 from 2000 with 230k kms on the clock. I've been looking all over the net in order to find a solution to a suddenly occurring weird idle issue of my Defender, now i've come to you and i would be very happy if you could help me out with this!
Problem is that idle speed suddenly rises, and then stays there for a while until dropping drastically into almost a stall, and then back to normal or a new almost stall that results in a rise. This goes on and on until it suddenly just goes back to normal again and stays there for the rest of the trip (mostly - it's pretty random actually)... Intervals can be both very long and not very noticeable or short and more violent, like the good old defender is pretending to be on the start grid in a fast and the furious movie (slight exaggeration!)
It's happening after a few kilometers driven and persist for about 15-30 minutes whenever i drive slowly without giving gas (no matter which gear, and of course the car moves faster when it occurs) or are stopping at a light. After 30 mins or a long drive without stops it's mostly gone. It happens mostly when weather is cold, but also when warm. It doesn't seem to have anything to do with how it's driven, and then sometimes the clutch pedal seems to affect it all of a sudden.
In the video below, which isn't the best of examples because it doesn't shift in idle speed as much as other times, revs are higher than normal and a bit rough, then i press the clutch and idle speed shifts to normal and then rises again shortly after (clutch still down). I've had the glow plugs checked and serviced and the wiring loom seemed in good condition. Also the red plug are completely dry without any residues of oil or dirt. I couldn't really explain the problem to the mechanic since it didn't occur at the moment i was there - of course - but he did tell me that it could be a problem with the fuel pump. The pump is running silent and smooth though... Have this problem occurred to any of you before? If so, i would really appreciate some good advice!
Aside from guessing there must be some kind of problem that needs resolving, it's a problem because it seems to disturb smooth gearshifts and It's also very annoying sitting at the traffic lights with an engine sounding like i kind of want to race the car next to
Thank you!
