I'm not prepared to 100% say it's sorted, but early indications would show that the idle problems on Gas are now resolved.

Any guesses at what I did?

I'll give you 2 clues:

1) I only identified the potential cause of the LPG idle problem when the car completely died and refused to run.

2) The replacement (upgraded) part cost me just over £35 on trade club.

HBV

Nope!

Although (obviously not advisable), the engine will run without a HBV

Crank sensor....

HBV

Also don't forget that, as you saw, my evap is fed from the bridge, so no HBV in the area. You're not even "warm"

[JamesV6CDX]

Crank sensor....

Nope! Crank sensor is on 110k and is still going strong - I was expecting you to get it first time, Mr DTM

Crank Sensor?

But they are a bit more than that aren't they?

Edit: too slow at posting!

CTS?

In which case battery......and if it is then it wont have fixed it coz when the engine is running it should have little effect.

Yes, the battery failed. Old halfrauds crap anyhow, so I replaced it for a VX Go battery for a 3.0

For a long time, it has been suffering from "flickering" of all lights etc on idle. This is instantly resolved with new battery, and idle is better on both fuels. It used to shudder on "eco" on either fuel - now doesn't.

I agree with what you say, but when I put the new battery on, fired it up from cold, it was absolutely fine on gas.

My reasoning is this. I rekon there is a poor connection in the alternator to battery positive+ cable. This is confirmed by the terminal getting hot and wire looks bad.

So, I rekon the old battery wasn't beefy enough, and giving intermittent power to the Gas ecu (which comes directly off it).

So - I rekon I need a new cable.

Either that - or there may have been a poor LPG + connection which I've corrected by taking the terminal off and back on....

Anyone got a p/n for a new + cable?

Don't you have one on the 3.0 Breaker?

There your are......its not the battery at all....you just have a short term reprieve thanks to having a  nice fully charged battery.

You need to sort out the battery charging to fix it..........so the real cause is alternator and/or connecting cable

Ok ok.... maybe I should have said Problem "identified" rather than resolved - but you knew what I meant

[JamesV6CDX]

Alternator is almost new, so I'm sure it's the cable. Anyone got any ideas on a price from Vx?
