o2 sensor check engine light code.

And check all the fuel system stuff, leaking injectors etc, then check for air leaks; intake boot, manifold gasket leaks. Good luck I hope you figure it out as inexpensively as possible. And I would defer to jlevie, you are supposed to replace it at 100K.

thanks guys. any other possiblities?

Now it dies goin down the road? O2 sensor?

you can test the o2 sensor with a digital volt meter and backprobes. The voltage from the signal wire ( make sure you have the right one ) and ground should vary between .1 or .2 volts and .8 or .9 volts. Main thing is that it crosses over the .45 volt mark. However, if the air fuel mixture is wrong your o2 sensor will stay either above or below that point and may be functioning correctly

I think I found my problem. I connected the new aftermarket fuel pump with tape and I should've done it with silcone and wire connectors. The gas is seeping throw the tape and shorting out the fuel pump. That's the reason for the bogging and sputtering and shutting off, im guessing.

Gas is non-conductive and can't short out the pump. But if you din't make a secure electrical connection, the pump might not be getting full power.

Yeah the conections weren't very secure. So im just gonna pull it out and connect them differently and see how that works.
