So I just finished installing a new SR20DET (with stage II cams) in my 240.
I got it idling decently and got it to stop stalling every time I let off the gas (from load).
However I am having one major problem. The engine keeps trying to cut out from 2500-3500rpm under low throttle. If I accelerate semi hard it drives fine, but as soon as I get up to cruising speed and left off the gas it starts having problems. The problem is most noticeable if I accelerate slowly in second gear the car abruptly stops at 3000rpm and sputters there.
As soon as I give it more gas the sputtering stops and it accelerates out.

Any ideas for what this could be are much appreciated!
