okay so my brother has a 96 GT. We have been chasing a problem for awhile. We are getting codes for bank1 & bank2 too lean, which the actron says common fixes are fuel pump (replaced with accel 500), intake manifold gasket (replaced). We are currently at a Loss, I'm attaching the datastrem from the OBD reader.
This car does have a BBK X-pipe, but had MIL eliminators put on. The car currently has the stock intake as the CAI made the issue worse. There does not seem to be a air leak as we check all over and can't find one? Someone please help us out we are done throwin parts at this car.

Replaced parts:
MAF
IAC
TPS
EGR
PCV VALVE AND HOSE
ALL NEW VACUUM LINES
INTAKE MANIFOLD (cleaned injectors and fuel rail)
02 UP AND DOWN STREAM
NEW MIL ELIMINATORS
FUEL PUMP (accel 500,high perf pump)
ALL NEW SPARK PLUGS


CLEANED THROTTLE BODY

Are you certain that the eliminators are good?

you have tackled everything even more than I did I had 2 issues.

crack in the driver head cover and worn out every rubber intake hose.

Did you replace the fuel filter?

either a fuel supply issue or its sucking air in from somewhere. Those LTFTs are sky high... Id find a smoke tester and attempt to triple check fro vacuum leaks.
