#1: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Thu Aug 04, 2011 6:17 am ---- hi,
im having major issues, on idle the engine looks like its got the shakes and its a little loud sounding with the wapping, ive just recently done a full service too.
i had a diagnostic done which was a waste of time because he said there are no faults and no em light but he thinks it could be two of the injectors (i already said i think its an injector issue before i took it in anyway) so i was no better off after this.
i've tried disconnecting the power connector to each injector one at a time but the engine still sounds the same, no difference in noise/shake factor, so logically this tells me that the injectors may not be at fault? next question is if thats the case what else could it be thats causing the misfire, oh and it also cuts out at times and struggles on cold starts too.
oh the car is a 1.4 hdi (8hz)
massive thanks in advance for any help
tim

Not a smart move with a HDI lump

#4: Re: 1.4 hdi misfire/engine shake Author: Seabook, Posted: Thu Aug 04, 2011 6:38 am ---- you can identify misfire cylinder bu a simple water spray test.
misfire cylinder will stay cooler than the others so it will take longer time to evaporate the water
#5: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Thu Aug 04, 2011 6:40 am ---- i've just realised where the manifold is bolted to the head there appears to oily residue, would this maybe suggest a cracked manifold and its blowing or a replacement gasket?

how do i do this?
#7: Re: 1.4 hdi misfire/engine shake Author: Abzynthe, Posted: Thu Aug 04, 2011 6:43 am ---- spray water on the manifold, and whichever one takes the longest to evaporate the water is the misfiring cylinder.
#8: Re: 1.4 hdi misfire/engine shake Author: Antknee, Location: ManchesterPosted: Thu Aug 04, 2011 6:46 am ---- thats easier said that done, the whole top of the engine has the intake system bolted to it
#9: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Thu Aug 04, 2011 6:53 am ---- so it all needs to be removed and the same with the rocker cover etc?
#10: Re: 1.4 hdi misfire/engine shake Author: MrrNoName, Location: UKPosted: Thu Aug 04, 2011 8:57 am ---- if there is a misfire why hasnt the ECU picked it up and put the EML on? i thought they almost always did with constant misfires?
#11: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Thu Aug 04, 2011 10:23 am ---- thats what i thought :S
#12: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Sat Aug 06, 2011 2:35 pm ---- ive located quite a few sets of injectors on ebay and local scrapyards, but none match my part number, but im reassured by all these sellers/scrapyards that all 1.4 hdi injectors are universal? is this true so it would be a straight swap job?
#13: Re: 1.4 hdi misfire/engine shake Author: Seabook, Posted: Sat Aug 06, 2011 2:41 pm ---- i would be very suprise if the injector is at fault
diesel injector is very reliable
#14: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Sat Aug 06, 2011 2:51 pm ---- what else could cause this? ive done the screwdriver handle test to check for the rhythm of the tapping (showing the solenoids are working properly) but they all sound different so im not sure...
#15: Re: 1.4 hdi misfire/engine shake Author: Seabook, Posted: Sat Aug 06, 2011 3:03 pm ---- lost of compression will cause misfire too.
if you really believe is the injector issue you can always get it check first, any diesel specialsit can do that. will cost less than 20 quid per set and if they are at fault, they can also re-con it for you.
#16: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Sat Aug 06, 2011 3:24 pm ---- firstly they charged 35 for a diagnostic, which didnt show anything because there was no engine management light apparently, so they somehow come to the conclusion it was 2 of 4 injectors. i got quoted 130 to test the injectors and i thoughts thats too much money to waste on just 'testing'

i tested mine for 20. even re-con injector don't need 130 for a set.
you have been robbed
#19: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Sat Aug 06, 2011 3:30 pm ---- good thing i didnt get it done lol. wasted 35 on a stupid diagnostic though! lol
#20: Re: 1.4 hdi misfire/engine shake Author: panzer360gti, Location: UKPosted: Sun Aug 07, 2011 3:06 am ---- I had the lumpy idle issue and found that the air intake had a leak, tighten up all your jubilee clips around your intake, also leaks in the exhaust could cause it.
Unless everything is perfectly air tight I think you might still get some kind of lumpiness.

#22: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Mon Aug 22, 2011 2:48 pm ---- now sorted, all four injectors replaced, new seals and protectors, new rocker gasket = runs like a brand new car again - please move to solved
#23: Re: 1.4 hdi misfire/engine shake Author: Seabook, Posted: Mon Aug 22, 2011 2:50 pm ---- might i ask what fuel do you normally put it and do you added any fuel additive at all?
#24: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Mon Aug 22, 2011 2:57 pm ---- in general the standard fuel saver stuff at shell and redex when i feel its been running rich
#25: Re: 1.4 hdi misfire/engine shake Author: Seabook, Posted: Mon Aug 22, 2011 2:59 pm ---- sounds odd that the injector is giving up that early.
#26: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Mon Aug 22, 2011 3:05 pm ---- i think it had injector issues when i bought the car just didnt notice it until the fuel consumption started getting as bad as a petrol! this being my first diesel to i didnt know how the engine was supposed to sound so i assumed it was ok, till i realised the engine was shaking to death and misfiring like crazy, wondered why the stupid woman (previous owner) was in such a rush to take her daughter to the park!

#30: Re: 1.4 hdi misfire/engine shake Author: tim30485, Location: LeicesterPosted: Tue Aug 23, 2011 5:06 am ---- if you mean where you get your date/time/temp reading - nothing at all.
