Misfire/injector problem

[spanners73]

yesterday my clio182 was running sweet,I parked up and about an hour later went for take away and the car had decided to misfire & sometimes just run on 3 pots.
Low rpm it misses & hesitates quiet bad but wind revs up it pulls ok but has misfire still. I removed & refitted ht leads off coil & it ran fine,then after a while ran it again and was playing up again. I unplugged No2 injector as scanner gave p0302 code and once unplugged the engine made no change so I assumed Mo2 injector isn't working? Or could it be plugs/leads are knackered & simply not firing No2 cylinder up..
Any feedback would be great,thanks

sounds like the injector to me. That's how I diagnose the 3 that failed on my old 172 cup over the last 3 years. Got one of eBay for £29.99 posted magnetti marelli too. Don't go to ecp as their expensive and their discount codes don't usually work for the injectors. Gsf do weekend codes for usually 50% off. I started a discount code thread on here which me and a few others update weekly.

I fitted new plugs leads & coil & its sweet once again..plugs looks a million years old and since I paid a local French car specialist to do the plugs 18months ago I'm guessing I was ripped off but no worries little bugger is happy again
