i have a 87 nissan pickup with a z24 engine. the problem is it wont take any gas after 2500 rpm. i have replaced the fuel filter, and the fuel pump and its still the same. it idels fine. has anyone had this problem or might know what would cause this? idk if the injector is sticking or a computer problem or what. any sensior on motor that would cause this? when it gets to 2500 rpm is acts just like its hitting the rev limit. any help would be greatly appreciated.

Check to make sure it's firing on both coils. Since it has 8 spark plugs it fires on the intake and exhaust stroke. If the intake coil goes out it will still run on the exhaust side up until 2-2500 rpm, then it cuts out. The AIV filter above the coils were bad about rusting and dripping water on the coils causing them to fail.
