Why Did This Happen?

[Scorpion]

After work I went to the car wash to give the Surf her weekly hose down. The high pressure jet washer seemed to go on longer than usual so I thought I'd blast some of the c rap off underneath (still there from Weardale).

When the washer stopped and I started her up the revs shot up to around 3,500 and remained there for about 30 seconds before settling down to normal tick over speed.

Anyone have any idea why this happened?

[scotty]

dont know how that happened but if i,m jetting the underside to get the mud off i always leave the engine running.

cheers scotty

is it ok now? or does it do it every time it starts?
if it were petrol i would may be think that water shorted a temp sensor or throttle position sensor may be.
diesels dont have chokes so dunno.

Alternator?? maybe it got wet an sent out some strange signals?

[dieselboy]

wet and sending out strange signals?

Ha! Slim chance, Rod! Owned the truck for a year and that's the first time anything 'dodgy' has happened. Started it a couple of times since and everything is 'tickity boo' again.

By the way has anyone had any problems running corn oil (49p a litre at Lidl)? My veggie oil experience has been non problematic to date and don't want to spoil it now just to save another 4p a litre.

water injection.....
it pos sucked water a small amount into the combustion chambers thru the air filter.

if you ever get your aircon recharged for a laugh get the engineer to release his gas into the airfilter intake and watch wot happens at the rear of the truck

[slydog]

wot

wot happens

[mud skipper]

that took some time before some one asked

[mud skipper]

well seeing as you asked
when the gas gets sucked in the revs pick up and the fumes out the rear are like a f...king big smoke bomb has been let off. bro did it on my old surf when recharging the system, immpresive

It's a built in sensor on the 3.0l, it's half way to a 3rd gen so they installed a water sensor for dippy blonde hairdressers, so when following the satnav and it directs you through a ford it keeps the revs up so as not to suck water back up the exhaust.
