Ok fellow dodge guys need help. I recently replace my cat to a mnaflow high flow and a cherrybomb glass pack. And since then every now and then my check engine light comes on after a while of driving and turns off if I leave it off for a while. I thinking it just the o2 sensors I see two sensors comming right off the heads before the the cat there was nothing after it so I meed a little help. Thanks

Yep, sounds like a perfect case where doing the non-fouler trick will keep that pesky CEL off...

 

Ya autozone said it was egr vavle but they don't know crap. Lol

 

Try disconnecting the battery, booth positive and negative than reconect in five min...Im runing true duals with cherry bombs and original o2 sensors, I get check engine when cold starting, running threw a car wash...

If this fails, than you need a scanner to read the codes, extreme could be a cam shaft sensor going..sucks that yhe yellow light tells you $$$$$ and nothing else..
