extremely high idle, car vibrations, and other troubles - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am swapping a redtop sr20det into my s13.

I start the car (it is 37 degrees) and it will idle at 2200 for a while, then jump to 2500 to 3000 and idle there for the rest of the time

dropped everything in and am pretty sure everything is bolted up tightly. the car shakes at anything above 10mph tho. all brackets are in... I cant see why it would shake so badly!

I ordered the motor from osaka... I know... something happened, something fell thru... the motor came from osaka. It is an automatic motor mated to a manual transmission with an automatic throttle body.

The manual throttle body is on the way, so for now, the tps is not hooked up. that may have something to do with it.

so... if you know of anything that could be the problem, please let me know asap. the car has to be out of the garage by tomorrow!

thanks!

Sounds a lot like the AAC-IACV valve, I would try cleaning it out with carb cleaner, and also check your voltages on your throttle position sensor per the FSM.

could be as simple as a vacuum leak.
