Losing power on LPG
JumboBeef:
Hello all,
Lovin' our RRC, which we have now had for a couple of months. Runs perfectly on petrol and LPG: until today.
Driving along on LPG, and lost power: switched to petrol and all was well. Filled up the LPG thinking it must be empty, but it was already half full :huh:
Started it up on petrol, but everytime I switch to gas, it has no power. On tickover, or VERY slight throttle (0-30mph in a couple of minutes) all is well, but put your foot down, and it loses all power.
Am I right in guessing that it is plugs/leads which need changing? Which plugs would be best?
PS: no back/misfires at all.
PPS: thanks!
jay2578:
plugs, leads and dizzy cap are probably your starting point..... as to which ones to use...... someone will be along shortly im sure :grin:
Rossko:
Also consider clagged LPG filter, failed LPG solenoid valve or vaporiser, vacuum leak, jammed catflap backfire arrestor ... and check the radiator water level (seriously)

I topped up the water this morning. What does it mean if I am losing water?
Rossko:
If the LPG vaporiser is mounted high up, and engine coolant gets low, vaporiser wiil ice up in use - harder its pushed, the quicker it freezes. Generally accompanied by a big stink as well as power loss. Usual effect is you can start off fine from cold but it all goes wrong within a mile or two. If your LPG problems are still there immediately from a cold start, its something else behind them.
That's a symptom, and the LPG system may not have anything to do with the cause of water loss, although rarely vaporisers can leak water internally.
