Alright i have this problem every since i took the s14 sr from my 96 and put it on my current 98.....the problem i have with it is that....if i let the car idle for a good 4-5 minutes it wont let me rev past 2000RPM for some reason..? Its the same motor/tranny/harness that was in my 96...all i did was just take the whole thing and put it in my 98......and now the nissan comp wont read it...having the idling problem......i was wondering if anybody can help me out on this?

check your maf cicuitry might have a bad ground. something is causing your car to go into safe mode. most cases with the car not goin past 2000 rpm is usually maf related. so start off by checking that out and also check the ecu for any codes this might help you pinpoint your problem.

yup sounds like your maf is putting you in limp mode. unplug your maf and see if it runs better or the same.

yes my maf is kind of cracked as you guys can see in this picture towards the bottom corner....would this cause it? Never tried to see if i can run with the maf unpluged.

A crack in the MAFs plastic shouldn't hurt it unless something conductive got under it and messed up the circuitry in there. This is quite possible since your cars probably exposed to all the elements. Usually if you unplug the MAF the car won't start (not sure with SR). Check your ECU for codes.

ive never haven taken out the sensor so nothing could of gotten under it. I ran the car with the maf unpluged.....that didnt go to welll..

I hope you didn't drive with it?!?!?

Air escapes from infinitismal spaces in the piping= boost leak

Dirt can get in the cracked maf. I would try another MAF.

I have an S14 SR MAF sensor. Was from my Kouki S14 SR. I swapped in a z32 MAF. It's in great working condition. Let me know if you're interested. PM me or something
