Default Testpipe CEL

What's the CEL that is commonly connected with a test-pipe and some HFC's? Thanks.

Default Thanks BSK

After installing my HFC I have a 17544 - "Too Rich" code...but I am fairly sure that the connection between my HFC and the DP isn't as tight as it should be. I am hearing a lot more air around that area then there should be...


So I wanted to double check if it was really that code that was throwing that "too rich" code, or if I was getting that code due to a similar Test-pipe situation. Sounds like they are different, thanks guys!

Default Possibly, but it only happens at idle

when I am in Park. If I'm driving the car, and I cleared the CEL, it won't come back. But if I'm sitting and idling in park, then the idle will get kinda jumpy, sounds like it may stall out but never does, and the CEL "too rich" code will pop up.
