Answer: not very long! :evil:
I still have the problem and it is DRIVING ME NUTS :evil: :evil: :evil: :evil: :evil: :evil: :evil: :evil: :evil:
To re-cap:
RRC 1991 auto. We have owned it for about two months. Fine until a couple of weeks ago (start of this thread). Runs fine on petrol, no issues at all.
On gas, sometimes it runs fine, other times it feels like someone has fitted a remote control rev limiter.
This evening, I took it out for a drive (covered about 25 miles, town and country). First five miles or so (NSL roads), no problem, freely reved to over 4,000. Then, suddenly, it will not rev over 3,000 (approx). Try to rev it over this, and the engine dies (but does not stall, just drops back to tickover). Take your foot off a bit, and it will rev up to (but not above) the 'limit'.
Then it will clear and rev freely, then it will not rev over 2,000 revs, then OK, then not over 4,000, then fine, then not over 1,500 rev. And so on. And on.
If you stop when it will not rev, put it into netrual, it will rev as high as you want, no problem. Back into D, then you have a rev limiter again.
I'm no expert, but I don't feel there is a LPG blockage: surely the problem wouldn't come and go like this? Remember, if I cannot rev it above 1,000 in D, if I drop it into N, I can rev it freely to any rev speed.
New leads and plugs fitted last week . Haven't touched the cap, arm or coil yet. I even put LPG from a different station to my usual one in the tank tonight to see if that was the problem (no difference). I am losing some water (not a lot) but this might just be a red herring.
This.Is.Driving.Me.Nuts.

Help! Anyone, please?! I need to get this sorted asap.
Rossko:
Have you looked to see if there is a catflap yet, is it free ?
Looked at the mixer, make sure it hasn't come loose inside ?
Will you tell us what kind of LPG system you have, is it closed loop (with a stepper motor) ? Stepper motors stick.
Have you stripped the front solenoid & cleaned, to make sure that doesn't stick ?
Made sure front and rear solenoid electrical connections are good ?
LPG system earthing good (no wire under self-tapper arrangements) ?
Considered taking it to an LPG pro (could pay for itself in a few tankfuls) ?
JumboBeef:
Thanks for the reply. The answer is, I just don't know enough about LPG to sort this issue. So:
