Mazda /B299 problems
 

My truck bearly runs. It will go if you bearly give it gas. If you push the gas peddel down its like shutting off the engins. Release the gas peddle a little or feather it and it will run,What has happened to my engine? My engine is a B200

did it just start doing that all of a sudden? What's the weather like where you are at?

I'm no expert by any means.. first guesses would be distribution cap or spark plugs or something like the fuel pump. when it's cold and wet, sometimes you can get condensation built up in the distribution cap. I would also take your gas cap off and let the pressure equalize... I've seen a bike with EFI get towed a thousand miles after spending a night in some more extreme climate... once the gas cap was opened, it ran perfectly from then on. A prior car of mine used to have some horrid vapor locking issues like that when it sat in the sun too long... fixed by opening the gas cap.

My first thought was clutch or torque converter.
