Had an 8L S3, a B5 RS4 now I have a B8 S4
It's got injector written all over it dude, sounds like one of the jectors not firing to me.
Do you know we had an intermittant fault with the same cylinders injector, Bill seems to be of the same mind so I think were going wire huntin' yeehaw
ps Welly what size WMI nozzle are you using?
