petrol additives/injection cleaner very close to mot

[mcjacko1987]

does this stuff really work and if so what is the best at a good price?
im asking as my car has a misfire, iv changed plugs,coil pack,lambda sensor ecu reset,charged battery,checked earths. next step i'll be trying injection cleaner.
also iv heard that using this stuff raises emissions before dropping them and if i use it i will be sticking my car in for mot the same week, would it effect the emissions test so close to it being used?
im looking at products on halfords and come across one thats quite expensive for an what it is: http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_73 8853_langId_-1_categoryId_165750
could this stuff clear a fully blocked injector if one of mine is blocked. misfire only started after i unplugged the lambda where it connects to loom,but fuel light was on, and been trying so many things to sort it, it wont start at all now as its run out of fuel.
i used some redex just the once a couple of months back and im thinking could this have cleared some shit up and over time its gone threw to injectors and blocked it?
any help much appreciated guys

Wouldnt of thought it could clear a proper blocked injector, but for the price of it its worth a go, asda sell the stuff for 1.50 iirc :) dont have a clue on the emissions thing though :/

Your wasting your time and money.

You are better off filling up your tank from empty with say V-Power. It works out cheaper in the long run and will work a little.

I would also suggest replacing your injectors, or sending them off. http://www.injectortune.co.uk/index.html I've herd very good reviews about this place.

i dont want to replace injectors just incase its not them. im going to try the 1 shot redex. if that dont work taking her for diagnostic test then if still unresolved stickin a vtr in there rather than wastin money on trying different things to sort this one.
