Surprised nobody has mentioned water leaking into spark plugs
on the 1.6 & 1.4 petrol engines ! judging by other threads on here
it appears to be very common, I've just had this issue on my own 55
plate Zetec 😞

it was on the first page 🙂

Was there a more I. Depth post on this issue? The cause and solution? Just seen someone ask about it locally is all and remembered this thread. But even in page 1 I dont see it referenced as artscot says it was on P1. 

Many thanks, Dave

The only references I have seen to juddering with this engine are in connection with the injectors. There was a problem around 2008 with a duff batch, and this was one symptom. It would also put the MIL (warning lamp) on with an Injector DTC stored. Hopefully on a 59 plate you are clear of this.

If it really was 18k rpm, it would not be juddering, it would be a miracle:laugh:.

I guess you mean 1800rpm, which is about peak torque on this engine. So it could be a lot of things from engine mounts to turbo actuator, via MAP & MAF sensors, EGR, intake hose leaks, etc. Most of these will be detectable to the ECU, which will store a DTC if it is sustained or serious. So I would keep a good code reader handy, and use it regularly, especially after it has a bad spell of juddering or it puts the EML on. Forscan is the best system I have come across, it can pick up codes that most basic, generic OBD2 readers will not see.

Check the EML itself has not been tampered with, it should come on when the ignition is turned on, then go out. Tampering with these lights is quite common, sadly.

Hose leaks don't normally cause juddering, but usually give an audible hiss as turbo pressure builds. The ones from intercooler up to the intake manifold are the most common ones to fail. Engine mounts can be inspected for visible failure, or for any appreciable movement under hand pressure. Failed mounts could cause juddering over a narrowish rpm band, due to some internal resonance.

Mate I don't know what a EML is haha I'm useless with a lot of car things im going to take it back to the garage I got it from I'm thinking egr or injectors it hasn't been drove for about 3 month proper so maybe it could just need a good run

All sorted now, i topped up my antifreeze which was mixed half and half and it doesn't do it anymore. The mixture must have been too rich for the temp sensor. So if you have this problem, make sure you try a 50/50 mixture first, as it is the cheapest option.

Thanks for whoever helped and I hope it helps you
