2096 - next steps?
2004 base Model, man trans.
i've read through at least the last 6 most recent threads about this p2096 code (bank 1 Running Lean) and I can't seem to kill it.
I see that a special scanner is required to clear it permanently but I don't want pay to have it done if I haven't actually beaten the code since it will come on again.
or side question? what the cheapest scanner/app I can buy this will clear this?
Recent Repairs So Far:
Replaced fuel injectors, exhaust-manifold gasket and bank #1 O2 Sensor (NTK)-
After the first couple repairs the light came on immediately but after the o2 sensor replacement the light will actually stay off completely until i start the car again.
Does this part hold any clues into what I should do next?
What i gather so far from reading on here is i need check exhaust for leaks before and after the cat and check for vac leaks. which i will do asap. not really in the mood to buy a whole new cat/exhaust system, as some people have claimed worked.
What would you do next?

ooooph. no window machines here. every time i try to use one i come within inches of smashing. switched to mac about 15 years ago. But if this saves me a ton of $ then I may have to bury my hatred and give it a go...

I finally did the smoke test and the only place any air seems to be escaping is from under the oil filler cap on top of the valve cover. could this be what's triggering it?
and thanks for the windows tipI will look into it if this problem persists.

I advice you to reset adaptive with INPA , and than do a new drive test.Also must check if your catalyst is not clogged.

I'm trying to work my way through that thread and it's make my head spin... this stuff is NOT my strong suit...
In the meantime, how do i tell if my Cat is 'clogged' without removing it? something is up and the car is still fumey smelling esp when I start it up and I just redid the exhaust manifold gasket.
Also never heard back about the oil fill cap. Should i worry about that being a place for air to escape?

Yes/No - it depends
The PCV valve connects from the valve cover to the intake manifold which is after the sensors. If the Oil fill cap is leaking and the PCV valve is old / worn or not working properly, you will have a open vacuum leak downstream of the MAF/MAP sensors.
Exhaust manifold gasket is upstream of the O2 sensors. Escaping exhaust upstream of the O2 sensor is one of the things that cause a lean code. Put some smoke around the exhaust manifold while the engine is idling and see if there is a leak. If there is re-do the gasket. ( I think those bolts are only 25 lb ft of torque so don't over tighten)
If you have fixed both the downstream intake leak and the upstream exhaust leak and if you still get the code. I would run a bottle of catalytic converter cleaner though a tank of fuel. IF you get the code again then you may want to look at the catalytic converter at that point.
Just my free advice which is worth exactly what you paid for it.

Another way to diagnose a plugged cat is to loosen (or completely remove) the bolts at the cat inlet, clear the code and drive it a bit (be careful to ensure that you don't lose the bolts or washers in the process) and see if :1) your power increases and 2) the code stays off. Yes, it'll be loud and raspy, but you won't need to drive it long to see if the code reappears.
