Mark, excellent description, many thanks, that's going to be printed and stuck on the wall. David, even more good info, thanks very much. Results of experiments: Oxygen sensors At 500rmp flicked between 0.4 and 0.5 and occasionally spiked to 0.7. Gentle revving gave reading of between 0.3 and...

Hi Mark, I haven't tried the adding fuel trick yet, and I'm going to have to ask if you'd mind explaining this in a bit more detail. How do I add the fuel? And where do I add it? Also, what do I look at on the Nanocdom when this is added, the live oxygen sensor readings? Is this something I...

Why not indeed :) I'll look at it in the morning. Thanks for the suggestion.

Hi Mark, the air filter looks fine (unfortunately - that would be an easy fix). :) David, I've just reset the adaptive values (after cleaning the MAF sensor) and am getting P0134 and P1000 faults - both suggesting no input the oxygen sensors. I'm very new to code reading and working out what...

Hello, many thanks for all your suggestions. Yesterday I purged the fuel system as suggested by sierrafery and the accelerator worked almost immediately, but the engine ran roughly for a few mins. Some success ion tracing the fault? This morning however, again after purging, it was back to...

Hello Marshall8hp and Mark, many thanks for your suggestions. I will make a start with checking fuel supply and pressures. In the mean time I cleaned the MAF sensor yesterday and the engine now runs very much better and the error codes have changed. I now have P0172 and P0175. I believe...

Hi slerrafery, I'll try that in the morning. Many thanks for the suggestions.

I could add that when starting from cold the engine often runs for a few seconds then stops. After a restart it again runs then stops, or ticks over slowly. Also, when running (and car stationary) tickover is reasonable smooth but as the engine speed is increased it get very lumpy around...

Hello, The engine on my P38 (petrol, 4.0 litre, Bosh) is not running correctly. Normal pressing of the accelerator usually slows the car. By pressing very slowly, and gently I can increase speed. Flooring the pedal also increases speed. Hills, even gentle inclines, are a struggle. Error codes...

Morning All, Help and suggestions with a starting problem would be most welcome. Disco 2, 15P TD5 rebuilt by Turner Engineering 10,000 miles ago (by previous owner, no idea why). In the morning the engine starts fine but the accelerator does not work for around 15 seconds. Once it starts...

And once again, thanks everyone for your ideas. Padawan, mmm, I think that that might be rather generous. I'm more at home with 1950s and 60s tractors. No suspension, no electronics and built to last. Anyway, the height sensors are my next line of attack. Cheers and Happy New Year to all.

I don't think the delay in raising this morning was a leak. It had been running with doors open for a while then nothing happened when I shut the doors. As soon as I pressed the 'raise' rocker switch it shot up. Mark's suggestion about the system being in 'pause' mode and needing a switch...

Good morning, and once again, many thanks for all your suggestions. It's snowing and -4 deg C here so I haven't done all the suggested tests yet but these are the results of some: 1) The cycling stops when a door is open. 2) I reset the height settings from Front Left 101 and Right 106, and...

Grrrrrr and Mark. Two helpful suggestions, many thanks. I'll start with the recording if I can find a record button on the Nanocom, and will look at the sensors when the snow melts and before the east winds arrive - I don't have anywhere under cover to work at the moment.

Hi RangeRoller, thanks for your reply. Set heights are: Front (l and r) 101 and 106 Rear (l and r) 110 and 102 When everything is stable actual heights match, or are one digit out. When the front is cycling actual height increase to perhaps four or five digits above set height, then fall to...

By the way, I would have checked the height sensor connections as several have suggested but whenever I have the time it's raining, or snowing! I'll certainly have a look when tome and weather allow. Cheers.

Hello, please can I ask for further help with my P38 cycling EAS, or dancing front end? I've had massive improvements to the EAS since fitting Kurt's rebuilt valve block but some problems remain - mainly the cycling between the the compressor pumping the front end up, and then valves letting it...

Hello all, Kurtjohnson10 is my hero. After trying and failing three times to improve two valve blocks with new o-rings (I've no idea why I failed) I bought a rebuilt one from Kurt. It works! There is still a slight leak on a couple of wheels but I guess that that is from one of my connections...

Once again, many thanks for your ideas. I agree that one problem is solved which has probably highlighted another. Good to hear that an indent in the plunger end is normal. I have lceaned them vry well, and the cone on which they sit, but did not grease them because I wondered if that might...

Hi Darth, thanks for your encouragement. I have to admit I'm struggling with this. If you weren't so far away I'd drive over with a large bottle of malt and pick your brains. A few days ago I sprayed the whole of the outside of the valve block with soapy water and the second solenoid from the...
