translation from idiot to somewhat smart

what is the rev limit on an '89 240sx? Also what would make it just shut down at 4000rpm's until around 3000rpm's then Accelerate again to the same point?It only does it in 3rd, 4th and 5th gear.

God that was like decoding hieroglyphics.

Now to answer your question,the rev limiter on a single cam is around 5700-5900rpm's,you might have a bad MAF.

 

He would notice the MAF on the way up the rev limiter more likely, not on the way down.

 

no it just acts like it is a rev limit. i can hold the gas the same and it just dies down then it hits a certin rpm and revs up again

 

Cts?

 

fuel pump? fuel filter?
when was the last tune up?
start with all of the usual stuff. then we can be of more help....
