Hi people, I have a 80 series Landcruiser and when the engine is cold it idles between 1500 to 1800 rpm. I've taken it a LPG specialist and they said alot of people compain about them idling high when cold and there isn't anything to fix it.
I am not convinced, so that why i was hoping someone else out there can tell me differently. :)
I live in
Perth and can someone also tell me where a reliable mechanic who can fix me head ache.
Thanks
Regards
Matho

Hi Matho,
I too have an 80 Series on LPG, but I cannot assist you I am afraid. One suggestion though is to maybe spray the throttle connections/springs etc near the carby with WD40 or similar lubricants. I do this every couple of months to keep everything moving smoothly.
CheersJust Do It!

Put two on first off.
FYI your cruiser will start on Petrol,before switching to gas at a certain time or rpm, so its not gas related.This type of rpm is fairly normal for the 1fz, and it can get bad enough for the timing chain to rattle a bit till oil pressure builds up.
The best way to fix it is to have the injecters done plus a efi tuneup, the cheapest way to fix it is what lcool suggests.

Had a dual fuel car for some years , even after I fiddled with it there was always a slight difference between the cold and warm idle but nothing like you indicate. Things to
check are the actual converter. There should be a drain plug in the botomto drain away condensation buid up around the diaphram. this should be drained every 6 to 12 months. The other major drama is that it seems that most installers are slap happy when it comes to the plumbing. they cut into your heater hoses without determining the direction of flow. The hose that goes to in of your car heater should have a Y-piece cut into it to feed the "in" on the converter.The out on the converter should then be connected by a Y-piece to the "out" hose from the heater. most of these installers return the converter hose back into the same line because it is easier. The trouble is that unless the heater tap is open the circuit is closed. Without proper water flow the gas does not properly change. You might also open up the water adjustment. These should go a long way to narrowing down the field for you. Good luck
