i new would do it regular glad to hear

[diffhead]

ps .. i was only kiddin.. its normal.. changed it recently and nothing on the plug. its just a bit strange that it behaves normally when turning the ignition off and on whilst driving... surely its electrical as a mechanical problem would persist?

[Sir Roofy]

would be electrical my guess youll have get under and check it for bare wires or loose fittings
could be any thing

[diffhead]

had a good look around all the looms but nothin is rubbed through and still flexible.. no hard parts apparent. do you know of anyone you could put me in touch with that knows about sensors etc?

I guessed you were in trucks from your post in the EGR thread.

did you like the thread? tried to make it easy

u callin me old? i started cleanin chimneys at 4 then changed to mechanics

The purpose of EGR had mostly been explained in the first page of the thread but your information about urea injection was new, and interesting. I've read a bit about urea injection on American engine websites, is it being used in Australia yet?

Quick forum tip for ya, posts like this make a bit more sense if you click on "reply with quote" so people can see what post you are replying to (like I did here). It's especially useful on fast moving threads like general banter and night shift.

egr.. hot gasses back into the combustion chamber reduces nox but increases particulates into the atmosphere. egr has only a few years to go before it wont make eu emmission levels............... dead duck......... scr .. injecting urea into the exhaust system to totally eliminate nox is only prehibited by the percentage of urea injected. also so far the price of urea pays for itself per km as it keeps the exhaust system clean and the engine working at full potential.

ive been workin with for 4 years

[diffhead]

basically you can make the biggest maddest 16 carbie 8 turbo engine you could imagine with 64 chambers and all you have to do is inject urea into the exhaust.... no emmissions

all new aussie trucks have had to be euro compatible for the last 4 years
