i have a 1990 nissan 240sx with the ka24e in it. i had the motor rebuilt because i thought that was the root of my problems but it still runs the exact same. it has a rough idle and will rev up in nuetral to about 6000 but as soon as you put it in gear and try to drive it it doesnt have enough power to move itself. i can get it to move at about 5 mph held to the floor in first and it wont go above 900 rpm when its in gear moving. i checked the fuel pressure today its good.the timing is dead on ive checked it multiple times. im at a total loss. any info would be helpful thanks

It wouldn't hurt to test the throttle position sensor, either.
