Red Lining

[BrownmanC]

Ok heres the situation....Its a little hard to explain so bare with me...Everyone knows when a car is redlining that the engine is starting to cut off..Well today me and Coastek started to put on my new cold air intake..Well when it was complete we started up the car and i rev'd...It was redlining at 2.8 rpms ( Dont get me wrong car sounded great but i wanted to performance   ) We thought we hooked somthing up wrong so we took it off and put the stock back on (So that i had a car to drive until we could figure out the problem) Well when we completed making my '92  240sx stock again the problem continued...Its redlining at 2.8 rpms ( its not possible to redline there but just pretend that ther is a red line at 2.8 rpms and thats what my car is doing..) I tried driving down the street...Yea that was scary..I dont know whats wrong and i hate not being able to drive my car   I cant get to a mechanic until Monday either...anyone know anything that could possibly help me? Or just a hunch about what it could be?  I would greatly appreciate it

I put on my cold air intake today as well. &nbsp;It did the same thing. &nbsp;Then I remembered.. &nbsp;DUH.. Hook up the MAF sensor dumass! &nbsp;Sure enough. &nbsp;It was just hanging there not attached to the MAF. &nbsp;Hooked it up, and immediately everything was hunky doory <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

2800 rev limiter, nice. . .

Check the MAFS, and reset the ECU, see if that does it (anybody wanna clue in on how to reset the ECU here?)

or if the maf doesn't help try posting same topics in multiple forums

next go to for sale wanted &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hmmm.gif" border="0" valign="absmiddle" alt=':hmmm:'>

sorry but odon't post the same topic in different forums thus belongs in tech talk (which btw it's there too)

Yes and i got different answers in both so it was a good idea &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> &nbsp; Hopefully i'll get it working today.. &nbsp;Thanks guys

i really should take the blame for this, i told him that &nbsp;i knew how to do it, b/c i've intalled a cold air intake b4, but i checked everything, and i just can't think of what i did wrong, i've resetting the ecu is fairly easy, so how do u got about it. well any advice would be good, cuz i'd really like to get his car running good, and out of my drive way. later <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/blush.gif" border="0" valign="absmiddle" alt=':blush:'>

Shouldn't your ECU be throwing a code at this point? Read the code, it will point you in the right place.

My gut feeling tells me that maybe you damaged one of the connectors on the MAF when you were installing your intake. I would do a voltage test on the MAF circuit to makes sure that everything is okay.

I mean what changed between your car stock, and messing with the intake? Something got messed up in between. Go back, retrace your steps, see what you "touched" and had to hookup again. 9 times out of 10 that is it. But I would check your ecu first, read the code. I posted a message a couple day ago for resetting ecu.

Please don't crosspost like this. You may have gotten more responses faster, but it makes more work for the moderators that really isn't necessary.
