I HAVE A SR20DE FWD, AND THE ENGINE DONT IDLE GOOD.
IT WORKS GOOD FOR ABOUT A MINUTE AND THEN THE IDLE GOES UP TO 3000RPM AND DROPS TO 2000RPM AND KEEPS DOING THAT,
IT HAPPENS EVEN IF I PUT ON THE AC.
WHAT DO U THINK IS THE PROBLEM.

I had that same prob in my SR20 carried by electrician (Rishi's Auto). He changed air flow sensor and ECU did some rewiring and have been working ever since. I had in a red top turbo ECU and matching air flow sensor (Selling it for those who want it) and it was swapped with new ECU and matching air flow sensor. Sometimes the A/C how wired can affect the ECU with feedback.

Perhaps u should be giving the defectives away than trying to sell it.
