Not really backfiring but more of a burbling, thudding sound coming from the exhaust. The car has never done this before. It seems to do at any rev range. At 2k rpms I was getting about 2 to 4 thuds per second. Any ideas guys? I'm taking pics of the old plugs now. I'll have the pictures up in 10 minutes or so. Thanks!!!!

Put your old plugs back

Pics? (besides "G-unit party")... what plugs did you buy?

I bought Bosch Super WR 7 DC, and for some reason the guy at Halsey gave me one WR7DC+. I didn't realize this until I was installing them. I didn't figure it would make a big difference. Any ideas?
Here are the old ones.

Makes a huge difference to how the car runs, that's for damn sure!

I'll double check in the morning though. Thanks!

Yep that's the one. Will it be fine mixed in with the others?

Old plugs look good.

And nothing has changed. Still burbling.
