every time i go up to 5k rpm, theres a limiter that wont let me go beyond that point. it happens in every gear...the stock limiter is supposed to be only on 4th and 5th ( if im not mistaken)...but this is weird. earlier today, it was fine. this happened all of a sudden. during the whole day, it has been running fine and even now it's running good. so what could cause the limiter?

it's so annoying...ineed ur help fellas

check your tps (throttle position sensor) Sometimes these end up out of adjustment all of a suddon because of poor tightening from a service or something. This sensor is on your intake manifold on the oppisite side of your cable linkage in a little black box.

the tps is on pretty tight. but it still has the same symptoms...could a vacuum leak cause this sort of thing? need help...

no, a vaccum leak wouldnt do that. All I can guess is its your speed sensor. Maybe its shorted or out of adjustment. I dont really know what to say.

maybe your car hates you, and its getting back at you for pushing it to much. 240's have a tendency to have a personality all on its own. That poor 240sx...tisk tisk...
