Background
Hey guys ive been having an issue with my car ever since i bought it about 2 months ago. It runs great for a few minutes until it starts to warm up then like you flip a switch it runs like crap. Ive replaced O2 sensor, fuel filter, 2 Mafs, IAC, TPS, FIAV, Intake manifold, plugs, wires and checked for vacuum leaks. I decided to try and purchase a cable to connect my computer to the obdII and try and see if i can find out anything.
Actual Problem/question
Ive never used anything like this before but the main thing i found is that all of the options in scanmaster ie engine rpm, air intake temps, coolant temps, short trim fuel, long trim fuel gave me readings, but when i switched to info for the O2 sensors i got 0's across the board for voltage(with one short jump to .020 for a second) and short trim fuel. I knew from reading about it that the O2 voltage should be jumping from .1 to .9 constantly or something like that so i think my problem lies somewhere with the O2 sensor/connection/wire for the O2 sensor but ive never used this kind of software before and dont know if i chose the wrong options or something so any help on whether what i suspect to be true is correct or not would be great. thank you!
