What is a eGo Starter Kit?


An eGo starter kit is two complete vape pens including; two small tanks, two rechargeable batteries and a USB charger. There should be some atomizers in the package as well.
Flip the tank over, unscrew the bottom, dribble the e-liquid down the side of the tank being careful not to fill further than the middle tube. Screw the bottom back on, screw on to the battery then press the button to vape. When the vapor production drops off or it tastes funny change the coil in the bottom of the tank, should be a week or two.

Ford 4.0 v6 misfiring


yes an o2 sensor can cause the mixture to go lean or rich. But you have another culprit also a knock sensor can cause this also. for the miss this is more of what the knock sensor would control. Hope this helps you

1995 Ford Bronco 172 EGO not switching lean bank1- jerks when run


Have u checked for vacuum leaks or poss leaking EGR valve? use carb spray around the upper intake manifold where it bolts to the lower manifold, spray vacuum lines where they are connected to the engine vacuum ports, the idle speed will change if u hit a leak, as far as the EGR valve goes see if it gets hot at idle, if it does it is leaking, if all checks ok replace the O2 sensor, but i suspect u will find a leak at the upper intake plenum.
