Knocking + $400 = Knocking!

Knocking + $400 = Knocking!
I've had intermittent rattling, which was diagnosed as knocking by Nissan - cause being bad ignition coils in my 2000. I just replaced them this week ($309 for the coils + $90 diagnostic) and the knocking all but dissapeared but then today I was able to find it a little bit again. It's far, far more subtle than in the past and I can hardly ever hear it (I have new plugs also and only use 93 gas), but is this something others experience, or should there truly be a way to get rid of this annoyance?

Yeah I kept the old ones So, I guess the only way to fix this is to replace them one at a time? It's so freaking subtle that it's really quite difficult to replicate. Since I did the work myself I can't go back to them and have them figure it out, and I think it would take a long time anyway since for the most part the coil works if this is the problem...but then I have to use one of my coils and I'm not sure which of mine are bad. Still, it's a starting point. I'll start doing them one at a time until I can try and find the bad one...

I'm guessing none of that would be covered under powertrain? I run out in about 105 miles and it looks like it will be difficult to get the car to nissan before it runs out. I'm going to try switching the coils again (I've done three and confirmed that if it is a bad coil of the new set it's going to be of the rear three), and if that doesn't work I guess keep looking...

your injectors could be dirty. Try cleaning it w/B&G product. Mine slight knocking was gone after doing so.
