Sr20det Help!

s13saru · 12-31-2004, 09:09 PM

OKay i got a 240sx withredtop sr20det and im having this idle problem....when i start the motor up it idles perfectly at 750 rpm and stays constant, when i drive the motor down the street and come to a stop the idles act like they want to die but slowly regain its 750rpm constant. ITs not my vacuum hoses, and its not my Mafs cuz ive replaced it and still the same problem.... When i ran the ecu fault codes it says 12 and 34 which i guess is supposed to be MAFS and knock sensor but ive replaced them and the ecu is still reading 12 and 34.... ARE mY fault codes correct?Ive checked my Throttle position sensor but im not sure whats the specs on the resistance, voltage. etc... if anyone has some INFO IT WOULD GREATLY BE APPRECIATED!

Sounds like a vac or boost leak to me.

Check your Intercooler piping for leaks.

I thought intercoolers were only on turbo'd engines. An Sr20DET is NA.
