The dreaded misfire....

[Techie88]

Gentlemen,
I guess this isn't a new thing but before I start spunking money on parts I would like to hear opinions.

Had my Clio 172 since sunday and it has a slight misfire on idle and is running around 800rpm and chucking the p0300 code. Runs fine other than that. A good friend (who's had clios) has straight away said that it's an injector....thoughts?

It's not bothering me much but if like to sort it.

Injector is usually a good shout but with it been the 0300 no specific cylinder id start by checking the quality of the plugs and leads first.

Thanks for the reply,

I've pulled the plugs amd looked at them this evening, they don't look the best but didn't have any to swap them with. I shall get some at the weekend along with a full service kit. May just need some tlc.

misfire code so will be an injector.

Thanks, from what I've read on here I thought it might be bit didn't want to spend out loads on different parts when most of you guys have probably dealt with the issues before.

I'd go with Bloke, pointing at an injector issue.
Simple enough to change over, and all too common to fail, just don't buy cheap Chinese copies.

I can ultrasonically clean injectors if you didn't want to fork out buying new ones.

Do you actually see any debris coming from the cleaning process? Or is the build-up microscopic?

as above, 9x out of 10 it'll be injector

Yeah you usually see the dirt coming out from the injector tip nozzle and it's left to sediment out after each injector clean. It then gets washed out before the next one is put in the bath of course.

Thanks buddy, bit far for me, I think I'll just get one new one and see how It goes, it's definitely not more than one cylinder.

Will keep this in mind for the future.

If you did want/need a pre-loved injector, i have a good few available.

I see. Is there an increased likelihood of injectors clogging up when the car is used for a long time on crappier petrol?
