My car spluttered again in the very same place on the very same road on my drive home from work. A smooth 30mph road; but uphill on a gradient of at least 12% (1 in 8). Last time was a month ago. I'm going to have to knuckle down this extremely intermittent fault, probably start around the coilpacks, as at my last Dealer service in March they changed my sparkplugs. (Not casting any aspersions though... :rolleyes: )

The only misfire counters I see are shown below; however I can't clear them. I've tried Clear Faults, then found a Basic Setting to 'Reset all Adapted Values' - but heeded the warning of possibly clearing all parameterization, so backed away very quickly.

So how do you clear these misfire counters?

Code:
IDE01975,Numb.of misfir.: cylinder 1,2280, 
IDE01976,Numb.of misfir.: cylinder 2,3255, 
IDE01977,Numb.of misfir.: cylinder 3,1236, 
IDE01978,Numb.of misfir.: cylinder 4,3449,

Hi Zenerdiode,
What do the fuel trims look like? Perhaps log them, the MAF and fuel pressures on the particular hill.
Regards HMC

Thank you HMC, but (as is usually the case) a bit of water has gone under the bridge. Intermittent faults really are the hardest ones to track down, but I think I've made progress:

So this misfire has manefested itself five times over two months, three times on that exact same hill, but a couple of times on the flat too. Latest one was just Friday gone; on the hill, but I managed to limp it another mile home to grab the VCDS lead, all the time leaving the engine jumping around and sputtering, clouds of white smoke from the exhaust. Here's the codes pulled:

Readiness: 0000 0000

Whilst running, I checked IDE00589,Fuel pressure,xxxx, kPa rel - and it was bouncing around all over the place. Stopped the engine, then KOEO (to activate the LP fuel lift pump) IDE00589,Fuel pressure, increased and then rapidly dropped to zero, I mean, like a stone. It's supposed to increase slightly with heat soak. This is suggesting an injector stuck open. Unfortunately didn't have any tools to pull stuff apart at that time.

This afternoon, did the IDE00589,Fuel pressure, test - this time holding pressure so the fault intermittent again. Without starting the engine I pulled all plugs; zyl1: slightly dirty, zyl2: normal, zyl3: filthy sooty black (there's my problem..!), zyl4: normal. I think injector for zyl3 has been sticking full open, dumping fuel like crazy.

Because the fault wasn't on with everything cold, I put everything back together and it started and ran well, but *CLOUDS* of smoke from the tail. My hypothesis for that is when zyl3 injector stuck open, it's washing piston carbon and then this sits in the manifold, turbo and cat. Initially I thought I had hydro-locked and burst something, but it cleared after about 4 miles of 3000rpm running.

Got back home and pulled the plugs again, this time all lovely and clean. All injectors read 1.6Ω. Thank you if you've got this far down; questions:

1. How likely is an intermittent mechanically sticking (open) injector?
2. Does the ECU switch the ground side of the injector, if so I could have an intermittent short to ground, however GDi injectors employ that inductive pulse from the back EMF, stored in a capacitor to 'generate' a 60-80V injector pulse in the ECU output stages.
3. Considering 2. above, is the ECU going bad? I thought if it would fail with a constant output to the injector - it wouldn't recover.
4. Should I load the parts cannon with four injectors? :eek:

Injectors are phucked!
Ethanol anyone?
Add Marvel Mystery oil and MOS2 to fuel and maybe you get lucky with fuel cleaner agent.

I'd change them......

Could swap locations for isolated test!

Get that oil changed!

Thanks mate ;)

I don't deliberately run E85 or anything like that, just what the UK gov decide what they deem acceptable in the British Standard.

Get that oil changed!

I know, I know. I may have seen a slight increase on the dipstick... :rolleyes:

1. How likely is an intermittent mechanically sticking (open) injector?

Do you have, or can you get your hands on an oscilloscope. IF so the looking at Rail, pressure, Injector Command & Current alongside the CKP will give you a 3 dimensional view of what is happening.

Another channel on O2 will tell you if it is going rich or lean causing the misfire.

Yes, I've got a couple of 2-channel DSOs; in fact, I've just taken delivery of a 4-channel Pico for work. I understand the charging curve, pintle 'bump' and all of that, but it's just so darn intermittent. I'd even thought of connecting the Pico and having it and the laptop permanently connected so I may capture when it happens - but of course the practicalities of that are somewhat different.

To give an idea just how intermittent it is, here's a rough history:

1. 3rd May, on the hill coming home from work, 5 seconds of misfire CEL set, CEL clears by the top of the hill.
2. 3rd June, on the same hill, again coming home from work, 7 seconds of misfire, CEL set, CEL clears by the top of the hill. (About 70 miles have passed)
3. 12th June, on my way down to Felixstowe, failed at Grantham, didn't clear when I was recovered, local garage thought it was the PCV valve (because of all the smoke) but by the time I collected the car, running normally. (250 miles have passed)
4. 22nd June, on my weekly shopping trip, misfired until I got off the road, I had a look under the bonnet, but ran perfectly when re-started. (400 miles have passed)
5. 5th July, back on the hill from work, this time misfired for the remainder of journey home, allowing me to do the diagnostic in my post 4 above. (220 miles have passed).

So it's definitley zyl3 injector stuck fully open that's causing the mis - but so intermittent.
