Yup, get a heavy rubber mallet and hit the cats if you can hear rattles inside. Well, sometimes its just annoying sound but the bung will get you a couple of years more. btw, whats your mileage?

 

I'll double check this morning but I don't recall hearing one. I hope that if there was one it would catch my attention, but I'll listen a little later today .it's about 25 degrees outside right now, I'll wait till it warms up .Lol

 

135xxx, around there .I live deep in the middle of nowhere .I have 5 miles of fairly rough gravel roads to travel every time I need to get out. Plus, an hour to any significant kind of stores .

 

I'm getting an intermittent 0420 on my drivers side. What length O2 extender do I need? They seem to come in a few lengths?
