what cause it to run erratic, like misfire,bad fuel,run lean,no power,

What is your question?

I did a jumper and it came up 44 which was the O2 Sensor, replaced that,EGR Valve, PCV Valve, checked all the spark plugs and wires they are good, but i was told about the tan with black stripe wire under the dash by the glove box and its connected, however i left the glove box off and while sitting still theres no change, but while Im driving, if i take a stick and jiggle the countless number of wires it will kick in and drive like its supposed to! I cant ever hold it still long enough to figure out which one it may be!
