While I change the MAF with a new one, I’ve noticed that the idle was running ruff and cause it to stumble and made the it add fuel to correct. So while it happen the CEL pop. So I’ve add 100rpm the Idle throttle put back the OEM MAF and driven 200 miles for the past 4 days without any codes...

Why don't you do long tube headers and get a good tune?

There is a long list of reasons why I didn't & won't do it in the near future and the #1 reason is money, the lack of a car mod budget that is. My Family comes first, second, third & forth in priorities, Camaro comes at the bottom of the food chain but at least it's in front of the Magnum and the Cobalt...

Anyway, by this time my P0174 or P0171 Cel would of popped again, I'm confident this issue is resolved.

I believe Idle RPM would fit in this description. Thank Ted for your help.

My CEL came on today but that's because I change my tune to make it run 14% lean so I just change it back to zero and cleared the engine code I'll just go get a tune from the professionals like everyone else
