unplugging things will run you in circles, if you are determined to fix it yourself, got to get some data.

Yeah. That's what I was thinking. Running lean. That's what the o2 is saying as well. Code for that. I just don't get why if I turn it off and back on it will run perfect for 30-60 seconds if its a fuel issue. Seems more like the computer justs poops on me for some reason and stops allowing it to run. I will attempt to check fuel pressure either way. Without it running the fuel
Pulse looks good and is crisscrossing normally. Once running it starts to choke after about thirty seconds even at idle. Wide open it will run down the road but I can't keep doing that either. Thanks guys.

When you start the vehicle it is in Open Loop, depending on temp and timers approx 30-60 seconds... so there's your answer. Same answer for WOT, it runs Open Loop = no feedback from O2 sensor, or it would be Closed Loop.

Yeah. If it runs perfect for that 30-60 seconds that's why it doesn't seem like a fuel delivery issue. Ill try and check that either way this weekend. I unplugged the o2 as you suggested to see if it stayed rinning good eaglemark. It didn't stay in open loop or if it did it didn't make it run in open loop and I still had to turn off and on to reset computer to drive it. I'm guessing every time I restart it and it goes open loop it starts dumping fuel like a cold engine til it reads the sensors. So still possible fueling issue.
