Hi Alex, without looking in my boot just now (its late and throwing it down), and maybe asking a silly question but u mean just the bundle of wires from the light cluster that run back into the car? must be if they near the hinge i suppose, they cant be fueltank related cos that on the other side anyway (over here anyway :).
Well im gonna take a look anyway cos i had a few gremlins in my car - a 93 Mk1 Ls400. It just jerks when i need more revs but lacks power when it does if you understand???? Its the only fault the engine has had and i dread to think of the expense.....but your info sounds a bit mad at 1st but i know electrics can do strange things so im gonna look and hope it is just a rewire.....
Thanks for the shout
Hi Manc,
Sorry. Been spending most of my time over on the U.S. site.
Being stupid, when I first found LOC and immediately joined, I didn't realize it was international and that I had joined the UK club. I have since corrected the problem by joining the U.S. site. Just now popped back across the puddle to see what my UK mates were up to. So sorry for the delay.
When you open the boot, at the left boot hinge, there is a wire harness concealed there on the hinge itself.
With each open/close action it puts stress on those wires. Eventually they fatigue then start to short out. This causes all manner of strange behaviour with the beast.
Everthing from (in my case) the stereo going on the blink, to bucking, stalling when brakes applied, to rough idle to surging. Really terrible experience.
I thought my beautiful world class automobile was pure junk and the engine, toast.
I finally (being a bit slow) realized that it must be an electrical issue, but had no idea where to begin to look for the cause.
Took it into the dealership (I know that's a big no-no here ;) ) to have them run an electrical check.
After 1 full day, they diagnosed the short at the hinge.
(My guess is that they knew from my description over the telly what the prob was, as it is an inherent design flaw).
They then offered to replace the harness at $500.00US.
I paid them their diagnostic fee, and politely declined.
Later at home, it was a matter of removing the plastic hinge cover concealing the harness, and stripping, reconnecting and taping it all securely together. Do Not arrange the whole mess so that it is stressed again.
In other words, let it swing free, in the open, relieving any stress on the bundle.
Not pretty, but.... problem solved as Ross Perot used to say.
Hope others with rough running, weird behaviour issues will see this and try it.
It has been smooth as silk since this was done.
Best of all, it's free and it works!
Good luck
(by the by, please post back if you try this and it works. The more people who learn about this easy fix, the better)
