Rb25det Revving Up at startup

[dannish23]

hey everyone, new to this forum, and new to these motors. I am currently running a '95 s14 with a RB25det swap.

basically what I'm dealing with here is that, AS SOON AS i start up the car, it revs up as if I'm pressing the gas, and doesn't go down. I haven't done anything to the motor other then replace the spark plugs, and i had drove it around problem free until just now.


i tried to search for a thread topic with the same issue as mine, but have had no luck. anyone know what this could be? again i haven't worked on the motor other then spark plugs, and as soon as i start the car it revs up as if i am slamming the gas pedal.

Have you checked the position of your throttle cable? I had mine jump out of position and rev really high
