kangarooing in spain

[Shaundon]

On holiday in Spain and in 40 degree heat we suddenly developed a kangaroo effect at random intervals while driving along. Can go for 10 miles or more fine then suddenly jerk/ juder as though id suddenly lifted foot from the accelerator for a split second. Was thinking fuel starvation but not sure why it would clear again and randomly come back if so?.

Perhaps electrical?

Seems unrelated to speed / acceleration.

Water in your fuel?

[Shaundon]

Possibly, anyway to test this??

Did seem worse after stopping to fill up but could be coincidence.

No it won't get in from filling up
It gets in through the breather pipes and filler assembly

pull off the outlet hose and let it empty into a glass
Water will sink to the bottom

remove the filter, empty it onto the tarmac, the water will bead and petrol will not

[Shaundon]

No sign of any water in the petrol, although strangely the petrol is a blueish colour over here!

Thinking given the random nature of this and fact it started in 40 degree heat that it could be electrical. Perhaps the coil breaking up ?

What sort of resistance should I get across the coil terminals and across ht leads?

all you need to know abaout coils^^^^

Might be worth cleaning out your float chamber, I have had similar symptoms in the past and found crystals floating in the bottom of the chamber, perhaps too many sugary compounds in the fuel, in turn occasionally blocking the hole. Easy check before delving in too deep on the electrical side of things.

Well after checking for water in the fuel system I removed a relay I installed with the tracker tk103b to disable the coil from a stop command on my phone. Drove 100miles smooth as silk. Don't know if its coincidence or the relay/ tracker were failing in the heat. Will see how it goes tomorrow...

Fingers crossed for you

Y'see when folks ask about stuff they don't tell you little golden nuggets of information.
It makes remote diagnosis almost impossible.

Well another 80 miles today and all well. Sorry kev but if I listed everything I changed in my van we'd be here all week and in my defence the tracker stop command to disable the coil has worked fine for many thousand miles upto now. Anyway thanks all for the help .

Ps Sunset over the camargue looks fantastic.
Bon nuit...

The fog over Anglesey was pretty impressive too
enjoy your hols.
