Peter Re the initial tickover RPM -yes it returns to normal 680~690 RPM after 20 secs, prior to the cure it was only managing about 800 and then falling to 450~500. No I hadn't changed the MAF. The subject on the Camshaft sensor is also very interesting as this could be the problem I have...

Peter, Very interesting your purchase of the OBDII Code Reader, did it come complete with leads etc? What site did you purchase from? Re My starting problem on Petrol - have now rectified the problem by re-fitting my old Air Flow Meter - this unit was replaced some 3 months ago and I have...

It's a BIGAS multi point injection system, Bosch Petrol system. Reg DEC 2000 ,V8i 4.0 , 7-seat, ES trim. 81,000 miles

Peter, many thanks for your input, much appreciated. Will check out the breather pipes, but it does not ring true when the "defect" clears, I would expect this to be a constant problem and not at each start up, and this is regardless of the engine temperature. The Servo system is "tight" and...

Re the MAF - on the Disco 2 the MAF senses the Vacuum and the Gas Manifold pressures which in turn must control mixture via the ECU even at idle speed which will obviously vary the Idle speed controller. Have exchanged Idle speed controllers with my mate's V8 LPG unit and it makes no...

Having checked all Peter's suggested areas, nothing found to be causing the initial staring and running problem. The only common factor between no servo effect( lack of vacuum) and the uneven running could be the Idle Speed Controller(ERR6078). If this is not controlling or open too far this...

Many thanks for your reply, will investigate each section in turn, but having already checked pretty thoroughly all above, can't see anthing obvious.

Have been recently experiencing poor, erratic initial starting on Petrol, does not want to rev and the brake servo appears to be non operational- hard pedal and no braking effect. Initially thought that there was a vacuum leak problem, but nothing untoward discovered. Within a few seconds the...

Having similar problem with Passenger side door mechanism on my 2000 D2, attempted to remove lock assembly, only to find that the pillar/window guide prevents lock assembly from being withdrawn. Has anyone got any ideas as how to remove the lock without major surgery to the door? It appears...

I take it that this a single point injection due to the age of the vehicle? You will have a fuel/LPG c/o switch and LPG LED level unit -yes? is this selection switch selected correctly and only set for LPG? Newer multipoint injection set ups only allow start up on Petrol - possibly some fault...

If the brake shoes on the front are not at fault, check that the flexible brake hoses are not acting as non-return valves( locking in brake pressure on the cylinders) However unusual for both to fail at the same time. More likely that the shoes or the springs have failed, or some cowboy has...

What carb is fitted? if it's a Weber, then check the fuel inline filter at the carb, this will cause similar symptoms.

If you go into web sites for Company's like Aut Gas, they supply a pamplet with all the LPG stations and also those who are certified LPG service agents and suppliers. The cost of the installation and equipment will depend on what Disco you have, the multi point injection system will be more...

Further investigation through various other web sites on LPG running problems has highlighted some problems with the MAP sensor which in turn can affect the air/gas balance via the ECU and cause RPM variation at certain loads. Has anyone else experienced problems with the MAP sensor on V8 LPG...

Changed vapour filters to no avail, still "hunting", experimented with various plug gaps -again no difference. Will have to bite the bullet and get some diagnostic testing carried out to see exactly what is happening within he system. the basic and more logical remedies have been tried. Anyone...

Changed leads today(who designed the positioning of these coils and leads??) and still find engine running similar to before - possibly slight improvement, but stiil giving slight "hunt" when maintaining revs around the 2000~2500RPM range. Will now have to investigate the "Gas" side now. I...

Thanks for the response, much appreciated. I had previously checked this cable tension and had also thought that the Cruise Control servo linkage may have been causing interference with the main throttle response, but since changing to a new set of plugs with the gaps at 0.6mm. the "hunting" is...

Thanks for the feedback on my problem, but do not think it has anything to do with the vapouriser or temperature pre-injection as this would be more apparent when there is a greater demand for the gas, whereas this is at mid rev range the "hunting" occurs. Another member mentioned the "free...

Have posted couple of photos in Discovery Gallery showing hose arrangement on pump and throttle servo unit - however appears that the TDi has a different set up to that of the V8i.

Cheers Thanks for the reply, will attempt this method, however will also have to remove the JW piping to the vapouriser which runs accross this space. As a matter of interest what plug gaps did you use? The set I have just fitted are 0.6mm. as recommended by suppier for LPG use. However...
