Cat and Map Sensor Threshold Question
Hey guys,
I have a 2004 4.7 QC that feels a little sluggish these days... working really hard to move. I'm not throwing any codes but my generic code reader shows the O2, Evap, Air etc blinking...
Does anyone know the actual numeric threshold numbers for Banks 1 and 2 as well as the Map Sensor Threshold numbers?
My Bank 1 uppers are in the lower negatives -1.4 and -4.1.... no catalytic codes... but wondering if they are starting to die or if my map sensor is fubared.
Cheers,
Parker
