Think an injector is failing. Mpg went down a bit in the last two days despite me driving the same journey in more or less the same way. Noticed idle is a tad high and lumpier than normal. Tried seeing what I needed online but the usual gsf and ecp don't stock them. I kept coming across ones that fit the 172/182 's which I thought was odd. I'd have thought the duty cycle would have been too high for a clio injector to work. Any info would be appreciated. At the moment it's just a suspicion as I've had a few go on the Clio. Will be checking coils and plugs ASAP.
