Misfire at high revs

[grantynp3]

For a few days driving the clio low down revs driving is perfect but as soon as your going up through the revs it starts missing , sometimes it will go no problems but other times it's missing but today for the first time whilst driving to work hit high revs and started missing and eml light was flashing at me done a few searches but can't seem to find much on tapatalk , had it on a code reader and nothing has came up , I know the car had new spark plugs a month ago just a bit unsure of what to do at the moment , don't know a specialist in the South Wales (Newport) area either

Forgot to add it also does judder on idle can feel sat in the car

Sounds similar to mine, I know my fault is a injector though, maybe a thought?

Done the injector test today , can't see no issues with the injectors , replaced plugs and coilpack today , also had a whistle coming from the side of inlet so replaced map sensor as was snapped , now not sure where to go from here , maybe lambda sensors ?

Had that on my old ph1. Turned out to be lambda

same problem with mine. swapped the plugs and it got a tiny bit better but its still there and misfires and hesitates like pulls back.so im in the same boat.will just do what you do lol

 

[bloke]

how did you test injectors?

i didnt mate.. dont know how

Tested injectors by pulling them out 1 by 1 , remove fuel guard for easy access and if one doesnt make a bit of difference when you remove it thats the one thats nackered ,

Not injectors for me though , So far done plugs , injector test , put a new map sensor on , new coil pack , the next move is lambda sensors , havent got any codes showing so maybe a faulty one will see tommorow
