misfire

[Anonymous]

My car has an annoying misfire at idle. I hae just fitted brand new hks plugs, genuine nissan leads, rotor cap/arm and it made no difference :evil: . The ecu fault code check comes up all clear :?: . I did a search and see the MAF sensor getting mentioned quite a lot. How can you check this if it doesnt come up in the diagnostic check? Thanks

if it is high up the rev range or high rpm you get the missfire it might be worth checking your plug gaps.

hi m8
as you say the misfire is at idle i would be checking for a vacum leak.
you don't say at wat point the misfire goes so i'm assuming that its going as you increase the revs.
good luck
