Hello everyone,
I hope you can help me get to the bottom of a little problem that's even got Jon, the brilliant Landrover mechanic who sorts my R4 out from time to time, stumped!!
A while back, my 4 juddered quite a lot in all gears and all speeds, to the extent that I couldn't really drive her. Jon, (mentioned above), tracked down the problem to the distributor. Apparantly, where the two wires from the starter motor, (I think!), feed into the distributor, there was a tiny problem - one of the wires was coming slightly loose and causing the engine to short, hence the juddering and stalling. He crimped the offending wire back into place and all seemed well...
Two/three weeks later, the problem resurfaced. Wire was adjusted again, and off I went. Then the same happened again. This time, Jon said he accidentally left the vacuum-pump (??? - I think that's what he said!) disconnected when fiddling, and suddenly the engine was running smoothly. If I've got the terminology wrong, it's an insulated wire connection that runs into the distributor on the right-hand side as you look from the driver's side of the engine bay.
Anyway, even though the engine DOES run much better, I can still detect a slight lack of smoothness, a little 'jump' in the revs, particularly when the engine's just ticking over. Also, when idle, everything shakes just that little bit more than it should...
What could it be?? Is it the distributor, or is it something to do with fuel pumps/pipes, etc etc...???? I just get the feeling that it's a tiny little problem, (I hope!!), which only requires a little tweak or two, and then my 4 really will be flying!!!! Can any of you help us get to the bottom of it...?????
Here's hoping!!
Many thanks,
Chris
