Looking for some feedback on this, but I believe it to be the actual Denso Iridium plugs.
So I twice noticed over the past month a weird stuttering of the engine when I applied heavy throttle in order to accelerate thru a changing stop light. This is the only two times I have felt this, as I don't ever drive hard or am heavy on the gas.
So I went and tested it tonight and gave it heavy throttle not quite WOT, in 2nd & 3rd gear. I got the stutter and the ECS and CEL came on. The ECS light went away after turning the ignition off and back on; the CEL stayed on. I pulled a scan from the VAGCOM, and got returned 3 errors all regarding a cylinder misfire.
So I'm presuming that it's likely the Denso Iridium plugs that installed back before winter. I had already installed the plugs when I saw a few posts on the forum about our engines not liking the iridium plugs and that the platinum was the preferred/recommended plug. I left the plugs in because I never noticed any issues after installing them.
So do we think that it is indeed the plugs?
