If the problem is worse at higher speed and larger throttle openings I'd suspect a fuel pressure/delivery problem. That could be from a failing pump or sediment in the tank clogging the pump inlet screen. A pressure & delivery test (see the Benteley manual) should tell if either pump is failing.The car makes it possible, but the driver makes it happen.

I'm having a very similar problem. My problem only occurs after I've been driving for over 15 min and the engine is good and warm. It usually happens as I give it some more gas to get over a hill or changing gears. It only happens when the throttle is opened, usually around 3k RPM The engine bogs down, the car bucks and acts like it's being choked. The check engine light comes on for a short time while this is happening then goes away. It's throwing code 46, oxygen sensor.
Does anyone know if this error could occur for both lean and rich conditions?
I'm thinking it's a fuel pressure/delivery problem but I'm concerned about testing for it since it happens intermittently and only when the engine is very warm.
Any ideas?
