Sup guys, happy thanksgiving!

on my way back from my girlfriends house i went to Shell to fill up my tank. Like the usual i pump 93 octane and on my way. about a mile down the road i noticed some abnormal backfire noise. it would happen after i lightly accelerated and then let off the gas to coast. The back fire was a few seconds delayed after i let off the gas and were singular loud pops. Idk if this has something to do with the gas because i have gotten gas from the same station multiple times. Also, when i got back i noticed that my wideband was reading really rich at idle.

Heres the video, it's definitely not the best idk if u can even hear it unless u blast ur sound :/ thanks everyone!

Mine pops all the time
i love it

07 ss supercharged with 3" exhaust

 

this happened to me when i installed my dp and took it around the block for the first time, next start up it was gone. that **** was loud haha

 

yea its weird, it just started happening. you think it is anything to worry about?

 

no lol.
my car will do it real bad if i get into boost and brake quick pops like hell
just the changes in exhaust flow hitting each other really for the less technical description lol

 

ok, the main thing im worried about is the rich idle. ill see if it happens next time im driving

 

whats it bouncing between at idle

 

it wasnt bouncing, it was sitting around 10.1 which is really weird. normal it bounces between 14-15

 

so whats it idling at now

 

10.1
