First off all welcome to nico, second is that you probably wont get the answer in the Nico general forum. Post the this in the 240 forum.

This isn't our job. We shouldn't even have to say this. The moderator should have moved the thread already.

Sounds like a bum MAFS or poor connection. Look on the 240SX.org FAQ for "ECU Codes" and pull codes.

Yeah, you could check connectors and replace parts forever and never find out what's wrong.

It definitely sounds like it's in "limp home" mode since you can't rev over 3000rpm. Post back if you have any problems pulling the codes.

uh.... hook your tps back up?

I got my money on MAFS.

I think a disconnected mafs doesnt let you go over 2500 rpm, or less. I think. Could be malfunctioning I guess too, but I wouldn't know exactly what happens at that point. I know TPS does exactly what he's describing if disconnected though :-) Or really bad grounding, which was my problem.
