Issues with O2 sensors?

[hollars04]

I have longtubes and o/r midpipe on my 04 GT, i have put MIL on the back O2 and the computer read that it was my front two banks having issues. SO i spent another $100 for new sensors for the front, reset the car and STILL my check engine light will not turn off! I have spent about $250 on eliminators,
O2 extensions, new front O2s and the thing still has an engine light, if anyone has any ideas to get it turned off that would be alot of help!

Thanks,
Chris

What codes is it setting?

All I know when my buddy checked said it was bank one sensor one and bank two sensor one, he used the computer from a dealership he works at changed it to OBDII setting and that was the readings it gave.

Find out what the codes are. Sound like it could be lean/rich codes, slow responce or heater circuit codes. All of them will lead you in a different direction

With both banks reading you could be running lean or rich like what was stated above which could possibly be a bad maf...

Thats it! The heater code, I tried getting it inspected today and you can only pass with one problem now and i had two, one of which was the heater! It has been running rich I can definatly smell it.

check fuse #8. If it's ok then check for power to the o2 or ohm out your extentions
