Question about 1996 Toyota Land Cruiser
Hi after a mile or two the warning check comes on significantly reucing the engines power. The vehicle is convert to LPG but presently does npot run on LPG ue to the warning check light problem I guess. I rea it is an emissions problem. Any answers ?
Hi there. When LPG is used to fuel internal combustion engines. It is often referred to as autogas. More recently, it has also been used in diesel engines. Its advantage is that it is non-toxic, non-corrosive and free of tetraethyl lead or any additives and has a high octane rating of 108 RON. It burns cleaner than petrol or diesel and is especially free of the particuales from the latter. It sounds like the best option for your vehicle since gas prices are higher than ever, but there are two downsides. Firstly it has a lower energy density than either petrol or diesel, so the equivalent fuel consumption is higher, but since many governments impose less tax, it is still usually more cost effective. Secondly, some designs of internal combustion engine require the lubrication of petrol or diesel with lead or lead substitute, and LPG's lack, thereof, can damage valves or shorten their life. Engines designed for unleaded fuel, equipped with hardened valve seats, are suitable for use with LPG without added upper cylinder lubrication, so if you did not do this with your valves, this might be your problem.

Illuminates when the ignition is switched on. It should extinguish as soon as
the engine starts.
If it illuminates with the engine running, it indicates a malfunction with the engine management system. Have this checked as soon as possible.
If it flashes when driving, reduce the vehicle speed immediately until the light illuminates constantly. If it continues to flash, avoid heavy acceleration and high engine speed, stop the vehicle and have it checked immediately.
On some vehicles this light may be red - again stop the vehicle and seek assistance.
If it is safe to do so, try stopping the vehicle, switching off the engine, wait two minutes, then restarting the engine to reset the engine management system.
With the light illuminated, the vehicle is still safe to drive as long as no other faults are apparent with the engine. Have the vehicle checked by a dealer or garage as soon as possible to avoid any damage being caused to the catalytic converter
