Hi All,
Since purchase in 2006 my ultra reliable Disco as been a dream to own. Then in September it wouldnt start. The AA fixed my "exciter wire" but two days later it conked again. A new starter was fitted and two days later it conked yet again. It appears the new starter was duff and this was swapped at the suppliers expense. Thats when the fun started.
As soon as I started to drive it away from the garage something didn't feel right. At car park speeds (1,000 rpm) it felt "stuttery" as if the revs were on/off/on erratically. On the road, it pulled and ran fine apart from the 1,000rpm mark (typically 20+ mph, whiff of throttle to keep it moving in traffic) when it feels like a misfire/stutter/hunt.
It went back to the garage and after weeks of tests it was pinpointed to a STC 1734 throttle potentiometer. The prices in the UK were extreme so I purchased one from Les Richmond in Melbourne which cost £800 with delivery, insurance and customs fees. After several weeks it arrived in the UK and was fitted to the Disco.
All was well until last week when the symptoms arrived again. At low speed it misfires/stutters/hunts badly. It literally feels like its firing every 2nd/3rd revolution as it lurches through car parks. I also feel that it is running rough at most of the rev range but this could be paranoia!!!
Id love to know your thoughts. What would you guys do? I cant replace the throttle potentiometer every six weeks at £800.
Could there be an underlying problem not caused by the throttle pot which went away for a few weeks to confuse me?
Could the pot be faulty after 1k? It did arrive in a LR box dated 2004 which is very naughty!
Additional info.
