My Misfire Road Test Video

[JamesT5]

Hi

After 3 hours of uploading, the HD quality video of the Misfire Road Test is finally available for viewing on my Youtube Channel.

For those of you who want to take a look at the 8 - 9 minute video, here's the link.....

Well I can safely say the grinding under right lock is normal, might be worth swapping the steering stops over.
As for the engine, it definitely looks and sounds like it's not firing properly and Since you changed the coil packs round and put new plugs in, I would have a go at the dodgy loom.

Steering stops... another job to learn or possibly just take it to the garage. Thanks, I'll try that.

Interestingly, I've been reading the codes the last 2 days and the misfire is now on Cylinder 3, which had a coil pack labelled '2' on it that I took off cylinder 2 three weeks or so ago. I've now swapped it around with the coil labelled '4' that I had earlier moved to cylinder 5 and wiped the codes. I took it down the road, the misfire was still happening but when I got back the DTC reader said there were no codes stored in the vehicle computer, despite the misfiring.

I expect to see Misfire on Cylinder 5 to tell me that the coil pack is faulty (the one labelled '2'), and I also expect to see the Cylinder 4 problem come back due to the wiring issue.

My theory is that it's the wiring loom and one of the coil packs, because number 3 cylinder has never played up before. I've ruled out spark plugs gaps as between the misfiring incidents the car has run normally, and if the sparkies were gapped wrongly then problem would have happened immediately after cranking the engine over after changing the plugs.

Gosh, this is like a game of Engine Cluedo......

"I think it was coil pack 4, in cylinder 5 with the misfire" :wallbash:

I'll get there with it, eventually. Thanks for your help and if you come across a reasonably priced loom then please lt me know and I'll give it serious consideration. :beer:

Although I did realise that you can just swap the sides to save yourself 20 quid.

The other side to the coin is that if they're coming off, I might as well replace them with some lovely new ones, then I know they'll be as good as new and I haven't got to worry about them wearing out for ages.

Looks like a fairly easy job compared to the ETM clean. Did you need any specialist tools to get the stops on and off or will my Aldi socket set and a wheel brace do the trick?

[M-R-P]

I didn't even need to take the wheel off (Axle stands were for something else ;)). Just undo the 2 13mm (I think) bolts and give it a tap. :)

Even better, simple job then! I'm going to go shopping online later for some wheel stops. Ebay you say? :D

Thanks, you're a star!:beer:

I've just ordered 2 totalling £17.99 including postage, they should be here tomorrow and so I can probably fit them on Sunday (weather permitting). :banana:

Let's hope it sorts the issue out. I have noticed a thread on here where someone took their car in for an MOT and it failed because the tyres were rubbing the wheel arches. I'm hoping by fitting these it will stop that horrible sound and also prevent an MOT fail in March.

There's a service bullitin regarding the rubbing on these, if the test center is clued - up, then you'll be fine. Alternatively, take it to a main stealer for the mot, they won't fail it on rubbing.
Mine has new stops, new bushed and new shocks/top mounts and still rubs (yes I had the alignment checked)

Another known P2 trait then. :doh:

Are you referring to the 'gasp' sound? What am I listening for exactly?

I'm watching all your other car videos now!

Are you running an N2O kit on there or something?

[M-R-P]

big cone filter, no soundproofing and a gizmo of my own design that causes turbo chatter at higher boost. makes me happy and is good for frightning cyclists.

If you want to put the wind up the other motorists, fit some amber LED grille lights to the front of the car. ;) As long as they are amber when turned on no one can do you for it - "Hazard Warning Lights" :D

Firstly, if your EML (engine management light) is on and the car is misfiring, please STOP driving your car. You are going to do untold damage if you continue driving!

Secondly, i watched your video, twice, and can concur yes, there is a definate misfire but what worries me the most is the slight metallic noise i can hear when you hovered the camera over the engine. I know what an injector solenoid sounds like and the metallic noise is more audible than that. Which, is not normal. First things first, whip out the plugs and do a mechanical compression test on ALL 5 cylinders. This will elliminate a broken or damaged valve. You can also undo the airfilter box and listen to the engine on tick over. If you can here a popping or pulsing (with pressure) noise then one of your inlet valves is broken!

Make sure you pull the fuel pump fuse to do the compression test else you will get false results as the injected fuel will cause a phenomenom called 'Borewash'.

Write down the results No1 - 5 and report them here::: on the forum.

You've obviously been scratching your Ar*e trying to figure out the problem, so lets go back to basics and start from scratch, that way you'll leave no stone un turned :B_thumb:

[M-R-P]

Lee, what sound system are you listening to that video through ? because, other than the knock caused by the missfire, through my HD surround, it sounds just like mine, Graham's, P.A.'s and every other ME7 engine Ive seen. l do agree that driving it hard with a missfire is probably not good for it tho.

Logitech 2.1 in HD 1080p, powerful satelites with very loud sub. Also on my digital HD X-Fi Fatality headphones!

Granted, its gonna sound different than in the flesh but i'll be honest wiv you, its didn't sound right and there's deffo a metallic sound.

[M-R-P]

hold on, im gonna boot into a different os and find a vid of mine...

Ok, it's a short vid and there's a bit of messin' about but on tickover, the sound is the same...

Lol ;)

If you were talking about the pup-pup-pup-pup-pup noise you could hear over the injectors, yeah, that was the misfire :)

I wouldn't say you wasted your breath, a forum is all about different opinions and that's how people are helped. If people only took the first info they got, they'd be taking my advice and that's not always a good thing lol...

Thanks for your input. I did consider the implications of driving around with the engine emission light screaming blue murder at me but then at the same time when I visited the Volvo garage and had a chat to the foreman, he said that the light normally goes out if it's something relatively minor.

The first time the light came on I was driving to work and unfortunatley my route took me up a Welsh mountain!

bubba_1986 and wobblydave have agreed to sort me out with some replacement coil packs which I'm very grateful for, and I've got Dad coming around hopefully this weekend to help me solder the damaged wiring to coil 4.

If the misfire still comes back then, I'll likely bite the bullet and take to the Volvo garage for assessment. I'm hoping the replacement coils and some neat soldering will do the trick. I've never known anything like this on any car I've owned, but there again I've never owned a car with 226,000 miles on the clock.

By the way, I've just ordered a compression tester off ebay for less than £12 delivered. At least it will give me some peace of mind if I can test the valves.

Gosh, I'll have a workshops worth of tools by the time I've sorted this problem out. At least tools are an investment that I can use again though. :D

[M-R-P]

It's good to have lots of tools but on the flipside, it's not always good to ask a question to which you may not like the answer... ;) (don't go looking for more problems lol)

Well if I was unwell I'd go and see the Doctor. He might go looking for other problems and find something, in which case it's good to know. On the other hand, he could say, "No, you're fine", in which case you know you don't have to worry.

It's the same with the car, I'd rather know for sure than drive around not knowing.

I doubt there'll be a problem with the valves as I would expect to see oil leaks and blue smoke piling out the exhaust. I don't see any of that and so the acid test will be checking the valve compression.

I have listened to both engines. I think the sound is hard to hear because of the sound thats actually being picked up by the camera. I am going to reserve judgement as to correctly diagnose james car i would need to hear it in the flesh.

Maybe i have a tuned ear! Afterall, i'm listening to lots of different engines on different cars every single day, so i know a metallic sound when i here one.
Who knows?

There's a good chance that what you maybe hearing is the motor noise off my camcorder, because it does squeak quite a bit but it's less noticeable with other sounds going on around it.

Your "tuned ear" has probably picked up my camera motor noise. Congratulations to you sir! ;)
