zx2 problem

[jsmey2298zx2]

i got my zx2 about 3 months ago and i love it, its got power and good handling bout i ran into a problem after i started to drive it over long distances. if i drive the car for about 45 min to an hour i compleatly lose power about 3000 to 4000 rpm and the revs drop and i can barly drive it i know when its about to start doing it because at high rpm it hesatates so i ease of the accelarator and try to make it home befor it compleatly shuts down most of the time i make it and when i pull in my driveway it stalls. i changed the coil, spark plugs, and spark plug wires and it still dose it i have no idea what it could be, but sometimes it almost feels like the rev limiter is kicking in but i have no idea please help, i love my car and dont want to buy a nother one

honestly ive never heared of a problem like that.

I'd take it to autozone and have them scan it for error codes.

i did there is no codes that come up. the first time it happened i was on the highway and i keeped it under 3000 rpms and it dorve like that for a wile than the check engin light came on and i had a friend use his scaning tool and it said a misfireing piston but the light hasent come on the other times yet ( after haveing him reset the code)

check the plugs, replace the wires and a new coil, or do a compression check.

i changed the plugs wires and coil but i got no change. how do you do a compression test?

Did you gap your new plugs.

If it lacks power in the higher rpm range or under a load your fuel filter may need to be changed. In addition to that the gas tank may not be venting. Loosen the gas cap so a vacuum won't be formed in the fuel tank as the level of fuel goes down. If this works replace the gas cap. It's good that you changed the plugs and wires. Typically an engine will miss out under a load if the wires or plugs are bad.
