Unplugging the O2 when cold and start the car until hot, it will give a code but will run on the data the ECU has not from what it reads and trims, so it will run, not as it's suppose to but won't die. Change fuel filter before, while hot or under load is when more fuel is needed

So by changing the fuel filter and unplugging the o2 I can determine if maybe it's the o2 causing my issues right?

Absolutely not , Your 02 sensor when you start the car starts in open loop , then with time and temps 45 sec to 3.5 Min or above 174 deg then changes to closed loop where it gives a voltage to the ECU to trim the fueling for idle and part throttle , IF the trims exceed 1.250 / .750 for a given amount of time if fails and goes back to open loop so there is no need to disconnect the front o2 sensor

If you disconnect the front o2 it times out the same amount of time as above then fails to open loop

Proper way to test this would be to get a scan tool and see what the front o2 stft1 is doing , the front o2 is a very good diagnostic tool and will give you a lot of information if you use it

The fuel filter bad would be very very rare to have any effect on how the car idles as there is no load or RPM at idle so very little fuel needed

Thought about forcing to maintain the open loop and see if it does not die. Did not considered the trim exceed. Like I mentioned, change the fuel filter before anything else.

If it was a bad fuel filter then it would run right when cold

Stop spending money on things that isnt the problem , there has to be a member local that has a xcal

Wait- it would run right when it's cold or it wouldn't?

Cause it does run right when cold-

It's when it starts warming up under load that it bogs down and dies and refuses to start till about an hour later

That's right we both are saying the same thing, think is a misunderstanding.

this sounds like a fuel issue to me. almost like the line is getting gummed up under load... takes a while to settle back to the bottom...
