SE 3.4L V6, WHEN ACCLERATING IT BOGS DOWN, LIKE ITS GETTING NO GAS OR TOO MUCH AIR,
2000 Pontiac Grand Am

Have replaced the catalytic converter, the egr valve, 1 of the O2 sensors that it said was out, tested the fuel pressure regulator and it worked fine, replaced all vacuum hoses, spark plugs and wires, fuel pump and fuel filter, still running the same. It idles great, and runs great until you give it gas, then it bogs down, acting like it is either getting no gas or too much air. We are stumped. Help please!
