TD5 misfire

(1/3) > >>

age:
Any ideas on this one?  Cold wet mornings are here, TD5 defender has decided that 4 cylinders are enough and no. 5 can join in later.

If it was petrol I'd swear it was a wet HT lead......  Fifth comes in after a few miles - seems to be quickest if I turn off the engine once its a bit warm and then re-start - all 5 firing then mostly.  Might have to do this a second time if I try it too soon after starting.

Engine is early x reg TD5 with about 130k on the clock.  Ring any bells with anyone?  Cheers, A

GREENI:
There is usually an oil leak that runs into a multiplug on the loom somewhere......though I can't remember where......look for an oil leak 8)

thermidorthelobster:
The oil leak would be the one which runs into the ECU multiplug.  Disconnect the ECU and see if the connector is oily.

A duff injector could also cause this;  or, possibly, low fuel pressure from an iffy pump.

vtrdaz:
We've had this fault very recently too.
As the others have said, check for oil at your ECU - i think it's the red plug but i stand to be corrected - just disconnect and check for oil - 2 minute job.
If all's clear it could well be like the problem we had - the actual injector harness , which fails at varying points and is a common fault apparently.

The harness is about £37 from the dealer so it's not too bad and is easy to replace.
My advice would be check for oil at the ECU - if all's clear - then renew the harness - which you'll have to do anyway if there's oil there at the ECU.
