S13 hatch with SR20DET after driving for approximately 10-15 min motor starts to sounds like it?s running on 3 cylinders and doesn?t boost past 3.5RPM... it?s happened a few times. When on cold start or approximately under 10-15 min of driving it starts acting up, every single time.

I have checked spark plugs and there doesn?t appear to be a exhaust leak on the manifold.

It?s a rebuilt motor and I don?t push it or drift. Approximately 2500k miles on new rebuilt motor.

Any suggestions?????
