Rep Power: 0

OK, where do i start. I install my egg o2 sim. through the ecu. and run one wire to the o2 sensor. BUt when i still stomp on the gas it boggys down and doesnt want to go above 3500 rpms. I took it autozone and they a run i test to see what was causing my cel to come on, (something about the heat sensor in the o2 sensor was reading right?) It's a brand new o2 sesnor so i dont what the deal is. if any one could help me out it would be great.
