Recently my MPG has been getting less and less.  A few weeks back after passing its MOT i serviced my car.  New filters and oil change, including a full pot of diesel magic in the fuel filter.  Since then i have been getting less and less MPG.  When i got the car i could go nearly 600 miles to a tank, i am now struggling to get 400 miles, which equated to less than 30MPG.

Now i noticed this week that with the cold weather it hasnt been getting up to temperature, so i have a new thermostat on order which will be fitted at the weekend along with a full coolant flush. 

It seems strange to me that it has got so bad since i did the service.  I know the stat wouldnt have been helping, making the car run  on cold run (rich), but is there anything else that could be an issue.

Also, when cold, the engine sometimes hesitates and the eml flashes on.  This only happens when you lift off the throttle.  If you press the throttle again quickly the car will try to throw you through the windscreen.  This seems to happen as i change gear and the revs drop past 2000-1500 rpm.  If i let the revs drop to idle before letting up the clutch it is fine, but if i mistime it, it seems like it is choking the engine.

The eml light doesnt stay on, just flashes, and there are no fault codes stored. 

Sorry for the essay, but i would like to try and fix these issues sooner rather than later, its costing a fortune in diesel

Have you checked the obvious like.......diesel leaks around filter seal/collar, leak off pipes and air filter box and connecting hoses/pipes. Have you accidently dislodged a hose/connection whilst doing your service?

As Mick says, plus does it feel like the Turbo's doing its job properly, Maf sensor (if its got one) could cause bad Mpg, spongy power.

Other stuff not so obvious, brakes binding, partailly blooked exhaust.

Agreed Mick, but before delving further, I'd fill a new fuel filter with Forte and give it an Italian tune-up!

Also, use 'proper' diesel - avoid the supermarket-type juice.

He's done that with diesel magic.
Suppose it won't harm doing it again.
Supermarket fuels, .....err I won't touch Sainsburys smokes like hell but Asda and Tesco ok especially when they give you a voucher worth 5p off per litre

It seems to still pull really nice.  maybe a bit slower than it used to but not really a noticable difference.  It doesnt seem to smoke any more than in the past.  I havent had a good look around the bay due to the shite weather, but i will get it in the garage at the weekend when i do the stat. 

The EML when cold problem isnt new, it did that before the service, but then stopped doing it for a while during the summer, either that or i didnt notice it.  Im going to check the connections to the temp sensor for the ecu make sure that isnt causing a problem.  I had the egr off not long ago and cleaned it out, all seemed good.

It doesnt smell of diesel in the bay, or anywhere round the car, so i dont think it is leaking.  I had the leakoff pipes replaced earlier this year as one split.  It reeked of diesel then, so i would notice if it was leaking again.

Occasionally i have filled up at saisburys, but since it has been playing up i have run 3 tanks through it, one esso, one shell and one sainsburys.  All have yielded less than 450 miles to a tank

Your not alone with this fault my tractor (auto) does exactly the same you lift foot off gas eml light flashes.
I'm also getting around the low 400miles per tank
I had codes 34 injector timing out of range and 64 fuel quantity out off range. I got codes cleared 2 months ago now there back with avengence.
Ive tried whynes fuel treatment had injectors & pump out and tested changed air & fuel filter every 14 days checked the timing the lists endless would be here all night wrighting.
I'm almost totaly bald with frustration not even my local garage will look at it every time they see me coming they s**t a brick and hide. .

I get a quick flash of the EML on throttle lift off when cold and have done for months, but I'm getting around 41mpg general town and A roads and around 48mpg if sat at just below 70mph on a run.

Is the injector pump driven by the cam chain on the traktor? Could the cam chain have jumped a sprocket and put the injector timing out?

[damage consultant]

I had a problem some time ago when it shredded the cotter on the fuel pump and the nut fell off so engine stopped. mcallister fuel injection got it going but its never been the same we had a big barney bassicly I called him a usless a-hole that couldn't fix a puncture. yes its chain driven weve had all the front end off( belts and fan) and all the marks line up the only thing left it to replace the chain thats not a job for me.
the chain can be changed without taking the front end off engine to bits specialist job though.

[Andy H]

I don't know if the sprocket is on a plain shaft or a tapered shaft.

It might be that the cotter has sheared again and the taper is holding the sprocket on but out of alignment (or the keyways and cotter might be damaged and permitting sufficient misalignment to put the timing out).

There's two chains:
One connects the crankshaft to the pump, the other connects the pump to the camshaft.

As far as i'm aware it a tapered shaft as you say the keyway could be damaged think its time to look on flea-bay for a new pump. :-/

I'll very soon have my previous '98 TD Estate up for sale.
Had a brand-new pump and no.4 injector last year, and it's chipped too!
