2010 Renault Megane 1.6 Fuel Injector Replacement - Misfire Fix

406 parked outside

[@peugeotCitroen2CV]

Hi there, thanks for the comment. Still have a few 406s, the 2.2 HDi is being used every day and the 3.0 V6 is up for sale. The 2.0 is in hibernation. 2.2 Petrol in the 406 would be an interesting choice 170bhp if i recall correctly?

[@SzwarcuKX5]

BHP wise is a kind of story this. Some engines have a head from GTI engines (2 liter from 206 or 306 .... I don't remember exacly) and they have 170 BHP even if papers say 158 or 163. Ones that don't have GTI head, have around 160 :) Service box says, that mine has 170 BHP and the GTI head which is cool I guess :P And it sounds brilliant when you rev it high.

Great stuff, thanks for taking the time to upload it, my step-daughter's car has the identical problem, all the best

[@ppanczel]

I have the exact same problem with my 2002 1.6 16V Kangoo. Changed spark plugs. No. 2 looks the same as your No. 4. All the others look okay. Changed one ignition coil on the misfiring cylinder. No luck. New injector next week. Thanks for whits video!

[@alanporter2694]

I followed your video and it was a great help. Could not have done it without this assistance.

[@peugeotCitroen2CV]

Thanks for the comment, great to hear the video helped.

[@pauloisidoro2]

Thank you so much I have the same problem with my megane 2 1.6 16v ,I thought it was one of the coil at first .

[@peugeotCitroen2CV]

Great to hear you got the problem solved thanks for the comment

[@bootybandy]

Big thumbs up on a good job.

[@joematarc5245]

thanks, very usefull video. my injectors are just fine, ( 2 with 14.8 ohms, 1 with 5.1 and the other with 5 ohms). changed the sparklers, and coils, but the problem presist. no lights on the dashboard! next step, will be checking the exhaust pipe. my troubles started after I changed the exhaust pipe. maybe the mechanics left something inside, which is blocking it, or maybe the catalyst. I don't know anymore... very fustrating. but thanks to you, I could go through the injectors. thank you so much.

[@shanthkannan3858]

thankyou very much for this video, my megane is having the same issue but the misfire is in cylinder 2. i didn't get the original fuel injector parts, so i ended up buying from ebay china ones. i will test the resistance of these injectors as well. Many thanks

[@jakubzastawny3851]

I have Megane II 1.6 16v and I have the same problem. I remove the spark plug and engine starting better but still have some problems with fuel injectors and now i know how to do it and I will do it. Nice work. Keep creating this channel and thanks for help :D ( sorry for bad english) ;)

[@peugeotCitroen2CV]

Hi there, hope you manage to get the issue fixed with your injectors. Thanks for the comment and the encouragement. Also your english is perfect if you had not said i would not have known keep up the good work.

[@yaesuft7800]

Thanks for this very informative video. I have a missfire on number 1 so will tackle it myself after watching your video. 2 thumbs up

[@Graoeye]

Thanks, i cleaned the Injectors of my clio 3 1.4 16v using this video. Used MAP-sensor cleaner, 9v battery+electrical wires (to open the injector) and some electrical tape on the MAP-sensor cleaner pipe to create a seal/pressure for cleaning it.

[@peugeotCitroen2CV]

Ah, you basically flushed out the injector sounds like a very good idea that, thanks for the comment.

[@Graoeye]

@@peugeotCitroen2CV I cleaned them for fun.. (covid-19 time is sometimes boring) 2 injectors were a tiny bit dirty, after cleaning they had nice 'jets'. For cleaning the injectors, i used MAP/MAF-sensor cleaner. I put electrical tape around the spray tube of the MAP/MAF-sensor cleaner to make it fit into the top of the injector and create pressure.. After that i connected a 9v battery with 2 electrical wires to the injector so it opened and simply sprayed the cleaner trough the injector until it was clean. i also replaced the intake gaskets, they seemed to be really old... thanks for you help :-)

[@zizoclever]

Great video my friend. Lot of helpful tips for beginners that want to get started 🔥

[@peugeotCitroen2CV]

Thanks for the comment

[@hugofernandes7947]

Nice work, very informative!

[@ppn7]

thanks ! i have the MK2 1.6 16V and will use your tutorial for the manifold teardown. Don't forget to check the crankcase oring which may leak, same as inlet the 4 orings manifold.

[@Djexekl]

Good Job, Nice!

[@danalex648]

Very good ! That help me a lot ! Thanks

[@00zuu00]

Hi! Thanks for your video. I have one question, two of my injectors are leaking: if I turn the ignition on and start the fuel pump I can see fuel dripping from the injectors. These injectors where recently replaced by a workshop, while the original injectors still work good. Do you think they might be failing because they are dirty?

[@palusisko]

Really great work! I am going to change coils and even for it the video is very useful!! :-) Excellent idea is to use comments of steps!

[@peugeotCitroen2CV]

Great to hear you are going to change the coils, let me know how it goes.

[@Graoeye]

i did that too with my mk3 clio 1.4 16v, the maintenance history book told me that one of the coils was replaced.. and i want a reliable car, so i replaced the other 3 myself. It was quite easy to do honestly.

[@clevemonsegue5478]

Got A bad misfire on my renault, checked everything and everything was fine then something tell me checked my gas filters and yep that was the problem. Gas was not coming up powerful enough for the injectors

[@peugeotCitroen2CV]

Great to hear you got it sorted. Where was the filter located?

[@user-fl9if1qi8o]

Thank you for your video. I have the same vehicle and have found Injector 2 has failed following a bench test of all 4 injectors. If I install a replacement injector, do I need to program it to the ECU with the number written on the injector? Thank you.

[@peugeotCitroen2CV]

Hi there, From memory when i replaced the injector on this car there was no programming required, i think the diesels require it but this petrol did not. A fault code reader will say something such as out of calibration if that is required.

[@lahcenrerbal5893]

clean work !!!

[@peugeotCitroen2CV]

Thanks for the comment, it is one thing i like about working on a petrol engine is they are just generally much cleaner than a diesel

[@Sco0bY91]

I like watching your videos ^^

PLS HELP ME TO KNOW THE WRONG INSTALATION OT THE INJECTOR CABLE'S CAN COST MISFIRES. I HV A RENAULT SCENIC 1.6

[@peugeotCitroen2CV]

Hi there, hows the caps lock Regarding the injector cables, they are generally a specific length to reach each injector, it is quite hard to get them to stretch to adjacent injectors?

[@gambero972]

Nice video! For those replacing the spark plugs, here's a tip: put a bit of copper grease on the threads of the plug. It will prevent it from ceasing with the engine block, and will allow easier removal next time :) And do like him, don't over tight them, as it's the engine's block threads (aluminium).

[@peugeotCitroen2CV]

It is worth paying attention to the instructions from the spark plug manufacturers, a lot are already coated. NGK for example do not recommend cooper grease on them ngksparkplugs.com/en/resources/5-things-you-should-know-about-spark-plugs

[@gambero972]

@@peugeotCitroen2CV Oh I didn't knew some where already coated. I've bought many Bosch and they don't specify anything and don't have any coating. But that's nice to know, thank you !

[@michaelg8284]

Awesome, many thanks for your work and shared knowledge!

[@peugeotCitroen2CV]

Thanks for your comment

[@mateusz1399]

I assume that you also could measure resistance of the injectors through this connector at 8:46 before removing the intake manifold. Testing coil for spark can be done with test light connected to ground.

[@peugeotCitroen2CV]

It should be possible although knowing the right wire to probe to might be tricky.

[@user-dt5sk6yc1q]

What Wilsons do you do? Portadown? I be in Mallusk every Tuesday/Thursday. Great video and looks a nice clean example!

[@peugeotCitroen2CV]

I take a run to both of them from time to time, not every week but fairly regularly, the cars can be good subjects for videos.

[@Darren-DJL-1]

yeah the videos are great! keep them up, may see you at mallusk some evening!

[@Darren-DJL-1]

Did you go to mallusk on Thursday? Buy anything for a few videos?

[@peugeotCitroen2CV]

@@Darren-DJL-1 Bought my ma the Jazz that featured in the most recent gearbox replacement video, ended up getting stuck into it wire wheeling underneath it for a slightly over the top rust protection. Its been occupying the lift for the past month.

Well atleast itll be well protected lol. Im just back from mallusk there, it was bunged this evening!

[@user-ro8mt]

Nice video ;) what keys I need to replace injectors for a 1.5 dci?

[@peugeotCitroen2CV]

Hi, i think you need to pay more attention to the 1.5 there are different states of tune and variations between the years. Never actually changed an injector on one but i suspect they may need diagnostic equipment to calibrate the ecu for the new injector. Best to ask perhaps on the clio owners club.

[@stephaniesheridan5474]

Did you empty the fuel from the fuel rail? I drained mine so I could take it indoors (same car), and now I'm worrying that draining it was a mistake. Never changed an injector before so I'm a bit panicky ha

[@peugeotCitroen2CV]

The fuel in the rail would have leaked out, there is no real worries about bleeding the fuel system the electric fuel pump will do all that the first time the ignition is turned on you will hear the pump whirr, turn the ignition on and off a few times just to let the pressure build back up then start the engine.

[@stephaniesheridan5474]

@@peugeotCitroen2CV Thank you! Much appreciated. I was too scared to turn the car back on myself after messing with it so much...i thought it would blow up so asked a random stranger to turn it on for me LOL

[@lyubobg]

why did it produce smoke after installing the injectors back?

[@peugeotCitroen2CV]

The WD40 used to clean up the surfaces where the inlet manifold and injector went. It was just burning this off. The smoke cleared after a few minuites and did not come back.

[@terryjones7778]

I have a Clio D4F 1.2 16v and its started misfiring under big load. Like going up hill . I'll try the plugs first . But it is on 91k now too

[@peugeotCitroen2CV]

Hi Terry I have a video on this channel covering the clio 1.2 D4F throttle body cleaning it may be worth having a look at. However if the car is showing an engine management light plugging it into a diagnostics machine would be a good first step.

[@terryjones7778]

@@peugeotCitroen2CV its not showing a engine light this time . But i have sprayed the carb in the last 12 months with carb cleaner . But never taken it off to clean it . Its still on the original coil pack too .

[@Nad76]

My Megane 3 doing same when i cold starter but engine management light is not showing. Maybe is one injector just dirty? BTW really good video!!

[@peugeotCitroen2CV]

Dirt could potentially cause one injector to fail but not enough to trigger an EML. Hopefully this helps you to get to the injectors, one plus with these petrols is the injectors are fairly inexpensive compared to a diesel.

Quite a pleasant easy car to drive, a fair bit better built than the megane 2 although not as dramatically styled. The petrols are a bit gutless but better for short runs. The 1.5 dci is a good engine very easy run
