2003 Mitsubishi eclipse. When i push throttle to the floor to excelorate quickly it starts bogging and loses power. what could it be?

It could be a number of things. the first to check would be to see if your check engine light is on. that would indicate a bad sensor. if this is the case, i would think maybe a throttle position sensor, or map sensor. but if the light is on, have someone use a scanner to get the trouble code. most auto stores will scan it for you at no charge. if there are no codes, and no check engine light, the next thing I would do is replace the fuel filter. if it get clogged it will restrict fuel flow to the engine. finally if that doesnt help, then have the fuel pressure tested. you may have a weak fuel pump. if the fuel pressure checks out ok, then I would have a technician look at it for a diagnosis. if none of these things helps then you have a much deeper problem with the computer or wiring that only good shops have the equipment to diagnose and fix. theyre awesome cars though. I used to have one. good luck!
