Hi everyone,
So I am completely stumped at this moment.
1994 OBD1 Integra with B20/Vtec
Installed Skunk2 Ultra Street Manifold
Bigger TB
New Gaskets
Cylinder head was re-installed as well.
Upon startup, car runs very lean at idle.
I have flex fuel and wideband hooked up as well.
S.Trims tries to compensate, but does nothing.
I have also added up to 100% more fuel through the overall fuel trims, and still does nothing.
Sprayed carb cleaner all over the place, doesn't bog.
Like I said, at a complete loss.
See attached tune and datalog.
I don't think this has much to do with the S300 itself, but seeing if anyone can point me in the right direction.
Thank you.
very lean at idle after couple different upgrades, need help

never touch the overall fuel trims.
Get a professional tune.

The fuel trims were setup by my tuner.
I know the values that he had in there originally.
I was just changing them to see if I would get a different response.
