    Hi Guys

    I posted a while back about an intermittent misfire. So I sent my car back to Audi and after a long wait and sending my car back to them several times because everytime they said the misfire was gone it came back. They replaced my spark plus, coil packs, redid the wiring from the ECU but the problem was still there. They fed me alot of **** on the way aswell but now their answer to my problem is that they removed the head and found that on cylinder 3 the valve stems are warped???


    Has anyone had this problem?


    I am also struggling to understand how that would cause the misfire to be intermittent?

    It's never happened to me, but I'm thinking the intermittent part of it could be caused as the valve rotates in it's housing. Depending on how severe the warping was that could cause it. I'm assuming because the term 'warped' was used instead of 'bent' it isn't too bad of a banana shape! :)
