hi guys i have a 1991 240sx it wont rev past 2500rpm i belive its the maf but i have no way to check i need help i live in the south end of barrie please help!
Jesse
unplug maf and check idle or rev to see if it smooths out, If it does maf is the problem
if car runs the same with or without maf connected, its maf.
thanks for the advice! yeah it was working okay before i took out the stock intake and put in the new AEM one…
