Injector 4 / damaging misfire/ emission light.

[will_lliw]

I bought my first clio 182 a week ago. im just waiting for the insurance to run out on my old car (this thursday) and it will be on the road. I started it up on the drive ( been sitting 3 days) to move it. the car started and ran fine but then the emission light came on and the engine has a ever so slight misfire, it hasnt got a full misfire if that makes sence? the engine sounds like a impreza. i plugged it in to the diagnostics and it has come up injector 4 & also damaging misfire. I swopped 1 and 4 on the plugs but hasnt made any differance and was still on injector 4. i pulled the plug out of cyl 4 and was slightly wet but has a sprark. I think its the injector but am i missing something? are they common to go ?

Hold on, you swapped the 1 and 4 plug leads around and it made no difference at all? Or do you mean the injector plugs?

Nothing?

No even worse?

Sounds similar to the injector fault i had a few weeks ago, same fault message I has, number 4 is nearest the driver side. Easy enough to change, just get yourself a new/2nd hand working injector or complete working rail. 10mm long socket and extension is all that you need to change it.

I had this problem too, I had emissions light and misfire in cylinder 4, mine turned out to be a faulty injector so replaced that and it seems fine now but the light is still on, we think its an electrical fault I still have the destructive misfire fault codes too.

swapped the ht leads around on the coil. I pulled the plug off the injector and the engine remained the same, does anyone know the resistance of a good/ brand new injector? the only thing i havent done is put a led across the injector plug to see if it is getting a signal.

What is ment by distructive misfire? bad coil maybe ?

no, just the injector has failed. Just get a new injector and replace injector 4. the light will take a few hundred miles to clear.

Sounds like your injector for sure matey, I'll fire up autodata and see what the resistance values should be.

Does it really take ages? As I have had mine fixed (as far as running is concerned) and the light is still on, being a pain in the ass!

 

[The Fatty]

yes it takes a while. If you have RSTuner, you can clear the error code and it should go off straight away. This is assuming you don't have another fault or course...

Had the same problem with injector 4. New injector and then RSTuner to clear code and it goes off straight away.

 

[LukeW]

I've had many people try and clear the codes for me! Even Danlp6 with his CLIP couldn't sort it and we now think it might be a wiring problem or a UCH fault

Injector should be here tomorrow and fitted in the afternoon! Fingers crossed!!

well i changed the injector today, i put a multi metre across the pins fn the injectors and i was getting around 13-14 ohms. On Cylinder 4 injector i was getting 3.e ohms haa! problem solved and the light has gone out to ! just be sure to use plenty of wd or vaseline on the o rings so they slip in, i broke one but luckly i had a box of o-rings kicking about !
