i have a 89 240sx single overhead 5 speed, bone stock as far as i know. when driving first gear revs out fine to redline, along with second, in 3rd it cuts at 5200-5400, and will not regain pedal for almost 3 seconds. in 4th it cuts it at around 4200- never tried 5th, what would cause this? im guessing ecu and or/sensors. thanks chris

 

my 89 sohc does the same exact thing! 5th gear cuts at 3500 for me.

wtf, someone has to know whats wrong here
