I have a 97 5.7 vortec 4l60e tranny z71
the problem I am having is this cel keeps coming on and off .
I have already replaced all 4 o2 sensors , cleaned the maf sensor. and replaced my pcv valve and the elbow which was cracked.
I did notice that when it was straight piped I never had this problem. then I clamped these magnaflow mufflers on and seems like I am having this problem with the mufflers on only. Im just not sure I haven't had the truck that long.
any advice would be much appreciated thank you.
