As above, any easy way of telling? Lumpy idle, all other diagnosis has come up with nothing so is there an easy way of checking if my car has aftermarket cams? I saw someone mention looking under the oil cap but what am I looking for to differentiate normal vs afternarket cams?

got a link or part no’s please bud? Whats the issue with it passing through rear beam on a Cup then?

Done s search but no definitve answer. Any idea of correct part numbers for 172 Cup handbrake cables? And where to buy, and what aftermarket ones fit? Various threads saying not available at renault, or that Phase 1 cables should be used, other threads saying 182 cables fit. What's correct...

Ps my car is a 172 Cup

Hey bud! Pontypridd - South Wales! That would be awesome - pm me? More than happy to pay deposit etc!

Any idea folks? Seem to be sold out everywhere!

Yeah quite possibly I suppose! 🙈

Ok, sounds like we’re getting somewhere. No idea if it has aftermarket cams unfortunately, assume the only way of knowing is for a specialist to take it apart and take a look? it was an ex track car so it migjht have been messed with, but the thing that is throwing me is that the owner before...

Intake manifold prrssure at idle says 410mbar (410kpa) some one on one if the facebook groups aaid it should be 360mbar so my timing might be out? Be suprised if timing out as owner before last didnt have idle issues and belts not done since. Is that correct as I thought around 400mbar was...

Yeah battery all ok now showing 14.5v and still lumpy

Ok so here’s my graph data how does it look?

I do actually have a new lambda sensor here to swap in if it ever stops raining! I’d be aurpised if it was that though as the one on the car was new last September for the mot and also the live data seems ro show it switching correctly. Unfortuantely my scanner doesn’t do graphs!

Ran the data again last night, still running rich. At a bit of a loss now!!

Dont think the mpg is great, maybe 25mpg mixed?

Thats really helpful you checking thanks very much mate I’ve got 0.41v static downstream And fluctuating 0.740v to 0.09v upstream - which is almost the same as yours isn’t it?

Yes engine running - would a slightly low battery cause it to run rich though?

2nd bank on my data shows 0. 410v constant. Bank 1 varies between 0 and 0.09. isn’t this correct though as bank 1 is pre cat which should be switching like it is? Or are the readings too far apart?

Also the live data seems to show the o2 sensor is switching correctly as the voltage is varying?

i think it was the pre cat as it failed on emmisions at laat mot last sept can I just check where the upstream one is located?

Live data video here:

Ok so it had a new bosch lambda sensor last Sept and live data indicates its switching correctly so I doubt it would be that? Injectors are the magneti injectors yes. It had new correct NGK spark plugs Jan 2022 but done less than 1500 miles since. Only thing I haven’t done is HT leads but...

Anyone good at reading/diagnosing from Live data? LONG TERM (-20%) and SHORT TERM (flutcuates betwen -8 and -18%) fuel trims are quite hefty minus figures - does this mean it’s running rich, which in turn can cause a lumpy idle? So far its had: - new MAP sensor - new coolant temperature...

Considered changing injectors but conscious of not throwing the parts cannon at it to be honest! Are OBD diagnostics easily available to pinpont any issues?

Eg mats, boot net, spare oil bag in blue? Tool kit? Interested to know what came included with the car as standard! If anything actually came with it haha

Its not cutting out or anything just “surges” a bit on idle. I can’t recall from my old one whether its normal or not!

172 Cup - runs very well. Cambelt done under 2 years ago so not due. Idle becomes lumpy maybe a minute after cold start. I know they are fairly lumpy but what diagnostic procedure should I follow rather than firing a parts cannon at it? 😁 Its no biggie as it drives superb but wouldnt mind...

Looks lime its not been mot’d for a few years but wondering if angone owned by old Clio at any point - black 172!

They are great but I prefer my M5 as a suoer saloon platform. Bs7 was pretty expensive to repair but as long as you fine one where the usual common faults have been rectified…unlike mine! I ended up in a mk4 R32 after it as I missed a hot hatch!
