Clio 172 Cup issue
Discussion
My Clio 172 Cup had a misfire & chucked a CEL recently, was in a hurry so booked it in to my local garage & they replaced coil pack, plugs & leads. 1 plug had rusted due to the tube filling up with water (no idea where from) & 1 tube was full of oil, cam cover gasket.
Shortly after it was still not running right so it went back & the old leads that were put on were changed for a brand new set, temp. sensor checked along with a few other things. Oil & filter were changed at the same time.
Driven it today for the 1st time & it is hesitating at low/constant revs & on a trailing throttle, boot it & the thing still flies with no issues at all. Guessing it's a fuelling issue? Will check the air filter later, it's a BMC or similar & not been cleaned for a while so maybe that will cure it.
No, I'm no longer on cliosport & am not planning on renewing my membership hence asking on here, hoping somebody may be able to shed some light?

Most likely a dodgy injector.
Easy way to check is take the fuel rail off, put it on top of some blue tissue paper and turn the car over, you should see an even spray across all 4 cylinders. You could also check the resistance of the injectors.
A code reader would be a good start though if you have one, a lot of the codes are rather generic though depending on what code reader you have.

Finally got around to checking the air filter tonight before I book into yet another garage for further diagnostics.
I fitted a 2nd hand Espace V6 airbox & ITG filter just after I bought the car, so about 8yrs ago! It has been cleaned & re-oiled annually (apart from last year), this year it is starting to degrade so I am binning it & fitting a new filter, paper probably.
Checked what I think is the throttle body (immediately after the air filter, a metal butterfly flap on a strong spring) & there is a film of black oily substance on the inside of the butterfly, didn't want to mess around so left it for now - should I clean this & what with? May this have blocked or part blocked 1 or more injectors?
Would a bottle of injector cleaner be worth a try, if so which one?
If none of this cures it then it's off to another garage.

Dirty throttle body butterfly is normal. Cleaning it may help it idle slightly better if it's really filthy but I don't think it has anything to do with your fault. Clean with carb cleaner.
Have you had any warning lights again? Fuel pumps do fail but on the Megane at least wont throw a warning light whereas a knackered injector will do. Does it cough on idle?

I had the same, look at my topic: https://www.pistonheads.com/gassing/topic.asp?h=0&...
Injector it was, but the HT leads/sparks/coil pack all helped.
Where are you based, I still have the old leads/injectors on my desk?

Mines just had coilpack, plugs & leads - all required. Changed oil & filter as they were due, but only just got around to the air filter.
What are the chances that an injector should fail at the same time?!
I'm soon to be back in a Clio What are the chances that an injector should fail at the same time?!
£600 worth of 182 comes with a intermittent engine light so your threads interesting reading.

Right, but none of that fixed my fault. Probably the same with you.What are the chances that an injector should fail at the same time?!
Not sure why you're ignoring the help offered to you, I have 2 spare injectors you're welcome to try, a code reader too. Other have said for £10 you'd get your own reader.
You're asking for help, to dismiss it, then say you're off to a garage. Either take on board some of the advise or stop wasting peoples time. We're trying to help for goodness sake...

I'm not much of a spanner monkey, will leave stuff like testing injectors to somebody who knows what they're doing hence taking it to a garage.
All help & advice appreciated, was hoping it would be something simple I could sort but it sounds beyond my limited capability.

I learnt a lot of what I know about cars through working on my 172's myself, give it a go.I'm not much of a spanner monkey, will leave stuff like testing injectors to somebody who knows what they're doing hence taking it to a garage.

If you don't want to get your hands dirty, then why ask? Drive it to the garage, pay some money and get it fixed.
On other other hand, get stuck in and change some bits, it's a cheap car that is easy (generally!) to work on. FYI, the injectors are 5 bolts, pull them rail out, swap injector, push back in, 5 bolts. I changed 1 in under 10 minutes.
