Can ANYONE please help with this one?
I have a 1999(V reg)4.0 V8 AUto disco 2, milage 63,000 Lpg conversion.
The problem started with loss of kickdown on the auto box in the middle of a 200 mile journey, apart from that the car was fine.
When I got home and put the car in nuetral the engine raced to 3000 revs and stayed there.I switched it off and left it for a few hrs.
Next time I started the car the revs did the same, I opened the bonnet and tugged the acc cable to rev it higher a few times to see if the cable was stuck open, I don't think it was and the revs went down a few minutes later.
NO problems for the next week at all, starting driving and no high revs but still no kickdown.
I left the car parked for 2 weeks and when I started the car NO problems.
10 mins later after paying for the carpark I pulled out onto a main road and as I accelerated the car nearly stalled and both the sportmode and manual mode gearbox warning lights came on.
I turned it off, back on, same warning lights followed shortly by all the suspension, HDC and ABS lights came on.
The car would still drive at 2-3 mph but any faster would make the engine cough and splutter.
I was relayed home to Norwich and put the car into the workshop I use.
They say the gearbox lights are to do with the engine ECU not speaking to the gearbox. The ECU has been sent off for testing twice and they say it's okay. The garage wants to put in a new ECU anyway.
Any Ideas are welcome as I don't want to spend £800 on a new ECU.
Thanks in advance Mike.
