Well coming to the end of my tether with this motor now. Despite an exhaustive session on Testbook, a complete wire by wire test of the engine loom and all the sensors no faults can be found! For those not familiar with the problems, we fitted a recon. 4.6 back in October, did about 1,200...

What should a 4.6 V8 idle at and anyone know what the TPS value at 3,000 revs (stationary) should be? Cheers Bill

Started out with 4.0 V8 with SAI which died. Reconditioned (non-SAI) 4.6 V8 fitted in October, 1200 miles were done on petrol only with no apparent problems average mpg was in excess of 18. At 1200 miles a full service was carried out and the LPG recommissioned, shortly after this the...

Sent my ECU off to Lynx Automotive for testing and they have come back with it's complex repair, may be done next week, this has been going on for a good few weeks now and I am not very happy. Anyone had any dealings with them or know anything about them? Also anyone know where I can get a good...

Right we can't get the old girl to go closed loop, this means we are getting about 10mpg, reduced power and occasionally poor running. Lambdas were fixed at .5 so we have swapped them out for new ones and they now flip between .4 and .8 but no difference to the running. No other errors are...

Having a little problem the new engine. Essentially under certain circumstances it feels as if it's going to stall at around 1500 rev, pressing the accelerator overcomes it. It seems less evident on petrol than LPG. Tried dropping into third and it doesn't appear to happen and generally...

After all the tears I am having my 4.0 rePlaced with a top hat 4.6 engine but we are getting conflicting ECU advice; 1. It just needs the fuel map changing to the 4.6 which is in-built. 2. It needs reprogramming by a dealer or the likes. 3. It will automatically adjust to the engine...

Right head gasket done, pressure/compression test etc all fine, engine runs fine, but after a few miles the cooling system is pressurising enough to burst the hose to the heater matrix. Any thoughts?

If I fit a 4.6 block in place of the 4.0 block on my Discovery will I need to change the ECU. Cheers Bill

Got the dreaded slipped liner problem so rather than just change the block I have decided to bite the bullet and do the job properly, including a recon engine, no point in spending £££s and cutting corners, any recommendations on suppliers of recon engines that are not a complete arm and leg.

Had overheating problems on my D2, thought it was the thermostat but having now got at it I found that the bottom hose was poorly fitted nearly fell off in my hand:rolleyes: Anyway that's by and by and no **** taking but I am having difficulty locating the drain plugs on the block:confused: I...

Brought a nice LR 3.5t adjustable towbar for the discovery, but I can't fit it as the gas tanks and relocated petrol tank obstruct the bolt holes. On the near-side I may be able to cut the bolt down to fit or use a few extra washers but on the petrol tank side even dropping the tank doesn't help...

My Discovery is turning into a nightmare, disconnected the battery last just to see if it would reset the ECU, was surprised to find a total inadequate battery fitted and the terminals were rather loose, still new battery would sort that. Went out tonight to reconnect it and nothing flat as a...

Had a little problem with D2 which on diagnostics showed up as 14 faults, all as the result of a blown secondary air injection pipe. we replaced the pipe (eventually) and the mass air thing as that was obviously faulty. she starts and runs fine now but is still showing faults on all Lambda...

'02 V8 Need to get a replacement for the original as it is missing (Alpine R990 I believe) this is the one with KH amp, dozen speakers, cd auto changer and steering controls, so failing to find an original any recommendations on a replacement to make use of the amp, changer and controls...

Need to get a tow bar for my D2, some are advertised as TD5, some as 2/300 and some as fitting both. So who is right are they the same or not. Cheers Bill

My poor old V8.0i is stuck in the garage in need what I am told is N/S Exhaust recirculation pipe it's a Y shaped (corrugated?) pipe, which I have been told is out of stock at LR and the manufacturers have gone bust. They have no lead time on when they will be able to get more stock. Can...

Now got two D2's sitting in the yard mine and a colleagues 00 GS model also on gas, which he has just acquired. It has what sounds like noisy tappets, I know it could also be a leaky/cracked manifold yet to check that. The noise is only noticeable on idle and under load, cruising it's quiet as a...
