got a slight missfire, was just under low load acceleration and just as you boot it but started getting worse and now a constant splutter between 2-3k under hard acceleration.

anyone know what it could be? i plan on removing and cleanign the EGR valve as been told these often clog up but dunno if this could cause that problem or not.

i know NOTHING about these engines! and very little about diesels in general tbh!

 

could just be in need of a update,ford had a pcm update for this also if its a tdci could require the injectors reprogramming cause they have a habit
of losing them!!!

 

Always worth getting the injectors cleaned to rule these out, even a bottle of MILLERS diesel cleaner has been very effective on some.
tabetha

 

mine does the exact same even sneaked it into ford and had it on the machine saying no faults

we done the fuel filter(nightmare),loads of stuff but it toils to start from cold too but fine when hot

not much turbo pressure anymore either

mine is a mondeo 2001 y-reg 2.0 tddi ghia x estate 175k

 

40% of the ones ive done dont bring faults up 60% do. get your injectors programmed (all 4) this normally cures it if not as tabetha said ecu update at ford.

 

it is a TDDI not TDCI for reference.

had the fuel filter changed just a week or so ago and ran a bottle of wynnes diesel fuel system cleaner through it which has helped bring back some power but not done anythign to the missfire.

if i go into fords and say i want my injectors reprogramming with they know what im on about or what?!

and how the fuck can you reprogramme injectors anyway?! what does it entail?

 

can't reprogramme injectors on a tddi if its a early one they did suffer from this an a update was a cure.

 

mine is the tddi too and only heard injector issues on tdci

why would mine run just like a diesel aswell not a turbo diesel?

all pipes hoses checked,actuator etc,and turbo is fine?

sorry for hijack but ive sold this car to my brother and would like to get it sorted for him also

 

have you checked the map sensor it sits on the boost pipe that runs
along by the subframe.they get water in the mutiplug etc,also the maf
can play up.

 

yes read wrong its not a tdci then!

 

so you can defo have the ecu on a 2001 tddi updated at ford to cure this?

 

xr-stu, are you using supermarket fuel by any chance? These engines really dont like running on it. I know people say that the fuel is the same everywhere but i work in Dagenham engine plant where we made that engine and i have had a few people come to me with the same problem, so if you are, try using a branded fuel for a few tanks and see if it's any better.

If this doesn't cure it then it could be the IMV (I think thats what it's called) on the fuel pump. They were a common fault on them too. It's held in by 2 allen screws, and located behind the rad. It can be awkward to get to but it can be done.

FYI, the injector codes are printed on top of the injector, only TDCi's have them. If you unplug the 2 pin connector on the top of the injector you will see them. There will be 8 pairs of numbers starting with something like FO.

The injectors on these engines have to 'update' themselves but i'm not sure if it applies to the old TDDi engine too. It feels like its holding back under low load (up a sliproad is a perfect example) for a second then all of a sudden it's ok again.

Col cos1, you say the engine has done 175k miles?

Has it had a new turbo? I'd be suprised if it's the original one to be honest.

Have you checked the turbo actuator?

Dave

 

definately checked turbo/actuator? you know what theyre like for sticking when they get coked up they have a boost valve too. its all(nearly all) stuff that can be checked tho with diagnostic equipment

 

what year?

what engine output?

How many miles?

 

not sure if its had a turbo mate but the one on it seems fine,no real smoke,and actuator works properly

ive been in 1 with 50k and it went like fuk for a diesel this 1 have reminds me of an old escort diesel van

 

mines a 2001 115bhp TDDI and done 165k. just had the fuel filter changed and ran a bottle of wynnes diesel fuel system cleaner through it which seemed to help with performance but didnt do anything about the missfire.

i will try using some decent fuel, maybe shell optimax or whatever they call their diesel equivelent.

the injectors just look like std diesel injectors, a hardfueline going to the injector from the pump with no wiring, so i assume as theyre not electronic in anyway they dont need reprogramming?

whats the imv?!

 

Sounds like yours is not common rail - so ignore any comments about reprogramming the ECU / calibrating injectors...

Is the turbo boosting?
Is there lots of black smoke on acceleration?
Whats it like at startup?

 

starts fine, but sometimes missfires slightly for a second or two then is fine from then on. turbo seems to be boosting, although doesnt feel quick like some people have said it should, but its rapid in 4th and 5th though, 70+mph. i reached just shy of 135mph tonight on the clock, on a closed runway near me. so must be boosting.


no black smoke that ive noticed.

it was doing it again tonight (only notice it at certain speeds and loads) seems worsed between 2 and 2.5k in 4th and 5th. its like an almost constant splutter until it gets over 2.5k then it stops. dont notice it in the lower gears passing through those revs.

it still hestitates now and then when i press the throttle and sometimes feels like its lost power, like itll pull hard for a second then slow up a little. its hard to explain.

 

hmmm odd!

Have you had it checked for fault codes?

 

not yet no, im scared the last time i took a car to fords fora diagnostic session the results were "its fucked" in other words

 

take it to someone other than Ford then

 

i did! the other place said there was nothing wrong. ford realised that even though the ecu said there was nothing wrong, HO of 3500 at idle constitued as something wrong turned out to be a loom/ecu issue that was untracable and ended up scrappign the car.

anyway! in other news, i put 1/2 a tank or so of shell V-power diesel in today and may have made a very slight difference, although may just be my mind tricking me. will see how it goes over the next 100 miles or so and report back. fuck running it on that all the time though, Ł1.13 per litre i nearly followed through!!!

 

imv= injection metering valve, on the back of the pump, tdci only though!
