I've been given all sorts of cures on the various threads I have been on but I am not sure if that's the answer. What could cause the injectors to throw up this fault? the car does 30 mpg and goes like stink I would have thought if it was injector the these (mpg and top speed)would be affected. Also been told the head may have to come off to check the valves luckily I have an extended warranty which covers valves.
I am totally perplexed!!!!!
I have to agree with you if you have dodgy injector you will get a misfire under load end and also your mpg would have drastically dropped .
As I have said before forgive me if i am wrong but it sounds like your idle valve or somthing to do with your air intake .
Have you thought of taking your car to another Renault dealer or a very good independent garage .
Your car from what you are telling me has nothing seriously wrong with it .
There's no way round it you will need to get a diagnostic check done on your vehicle to find out what is wrong with it .
If it means spending £50 do it
When you get the diagnostic check done get them to check the fuel pressure reg make sure they do this .
Please update me as to what they have found
