Hi all,
I purchased 1995 M plate, LS400 about 6 months ago as a project, as it hadnt ran for 3 years, it was garaged though, it wouldnt start so I had to have the immobilizer bypassed, and a new battery, it then started first time, then MOT passed with just a number plate light out, which they sorted for me. I drove down the road feeling like a king never had I been in such a smooth quiet car, amazing. previous best car was my 7 series beamer loved that too, but, this just felt better to drive.
First job 4 new tyres, balanced and tracked.Next timing belt water pump and pulleys, then a new altenator as it failed and a service on the power steering pump, I then started to get a strange thing happening after start up from cold, I pull away and the speedo starts to bounce around, 40, 70, 120 allsorts, this must give the transmission mixed messages and the car does not know what gear it supposed to be in, or its like something has damp in it as I drive it for 15 to 30 mins and all of a sudden it clears and drives lovely again, so I found the post on here with ref to the ECU and sent away to america for the correct resistors and had them all replaced, car was then great for a few weeks, now its back, and its every time i leave the car standing for a day or so. I have now checked the wires in the boot hinge and all seems to be ok, I am at my witts end with it, has anybody had the same things go wrong for them as I cant find any of the same symptoms on the net or other forums, other things that happen are the radio lights are out but after 30 minutes or so they come on when lights are used and the ECT ( Ithink) light flashes not often but now and again. any ideas anybody please
Many thanks
Phil
