the car is trying to kill itself while idling because too much fuel is being dumped in and the motor is drowning itself basically. its running good at WOT because all the fuel is being burned up. This happened to me and it was because my ENG SEN fuse was blown

Update ok so this past weekend i got under the car and took out o2 sensors and cleaned them off, bent the slits out a little more and reinstalled my o2 extension set. The car was running great again.gas mileage was back up no idle or drving problems. So then sunday night i was drving it and i go to give it gas and the RPM just drop and the car stalls. I starts it back up and give it WOT and the RPMS just drop to around 200.. the car tries to stay alive but just dies. Now the car will do it when it is cold, or when i first start it. it feels as if it is running to lean and when i give it gas its just to much and air the car dies. Im thinking MAF maybe?? any suggestions?:brick:

Change the 02's. You cleaned them off a little and they worked for al ittle bit. Change them and then change the spark plugs in the car. After the 02's go bad, the plugs will be very black.

I had almost the same problem after I had my longtube headers installed. Except mine would only mess up when it was wet. I replaced the spark plugs, wires and noticed the o2 wires were getting wet and torn. I used a weather proof wire/connector and re-taped it all and it has run fine ever since.
