Thread: Nasty misfire on TD5

Check for oil in the red plug on the ECU.
The only time mine has dropped a cylinder was on a seriously cold start, and I think it dropped more than a few cylinders

My advice is get it seen to asap. Mine started like that and now the engine is totally knackered. Granted I drove it for a while ignoring the issue.

Sent from my GT-I9505 using AULRO mobile app

After inspecting the ECU which was very clean (i had the injector harness replaced about 6 months ago) i decided to contact SITEC who lives nearby - what great guys! - They came around and had a look for me and it seems i may have an injector problem. Was great talking to these blokes - crash course in what I may be up for by owning a Disco - I still love it though! Also eyeballed SITECS 101 - very cool

Thing that seemes different between my issue and the misfire issues dicussed previously on this site is that mine is constant and doesn't cause the engine to cut-out.

Did you have the codes read?
Could be the harness, dud injector or a whole host of things
I'm down south and have a nanocom if you need help, although there is probably someone closer - that is if you haven't read them already

Mine had a similar problem. At 100km/h on flat ground I would have hardly known only for water temp running high (only 95) on the MADMAN gauge.

The first and second time I fixed it I just unplugged and plugged in each injectior. The third I bent the connectors to make better connection then the fourth. I ordered a new harness and tappet gasket. I got the wrong gasket but the harness has fixed the problem. There was no oil in the old loom at all and I have kept it as a spare in my spares kit.

There were no faults when checked with Nanocom but the injector balance on one injector was all over the place. Most were running +/- 1 maybe 2 but one was upto 20.

Happy Days.

Joel, were those injector imbalances at idle or under load?

I haven't done a code read but will be taking it to PCB next week.

Temp is good at all revs and i can still pull 120kmh so it would seem that i am stil getting something out of the faulty cylinder

Stretching my memory now mate,

At all rpm if I recall correctly

Happy Days
