    Same bucking problem. Replaced O2 sensor and EGR valve. Better but still not right. Thinking it might be the fuel pump starting to go bad. The basic problem is it runs too lean.

2002 chevy express van 5.7 v8 error code PO154 Bank 2 sensor 1 oxygen sensor

That is a low signal error from the right bank upstream oxygen sensor. In most cases, it is caused by a weak oxygen sensor. Before replacing the oxygen sensor, double check fuel pressure, volume and quality. A low signal from the oxygen sensor can also be caused by a lean fuel condition.

have you had the throttle cleaned? Sounds like your fuel pump may be getting hot and cutting out. Its possible it could be a faulty ignition module,but that usually just causes a no start not a suptter and stall.

You can have an ignition coil going out and not throw a code. Need to have someone perform a power balance test to find out what cylinder is causing this. You might also think about changing fuel filter. A dirty mass air flow sensor may also cause erratic driveability concerns.

1991 astro Van 4.3L seems to run ok at low speed and the when going above 40 mph it bogs down. Could this be the carb or EFI?

This could be the carb or fuel injection system in need of severe maintanence but I would recommend checking a few other things as well as checking the fuel injection system or carb. I would also have the catalytic converter checked out and go ahead and perform a basic tune up (i.e. plugs, wires, cap, rotor, fuel filter, air filter). These are some basic things that can cause engine power loss. If after a basic tune up is done and the problem still persists, some other places to look are idle air speed cylinoid, M.A.P. sensor (Manifold Absolute Pressure sensor), and O2 sensor (oxygen sensor). These are other components that can cause the same reaction you speak of. I would recommend a lap scan diagnostics test be ran at your local auto tech. Hope this helps, good luck!
