Hi, just started facing this problem a few weeks back. Mine's a SR20DET with a VE conversion.

It sorts of misfire slightly at random times, usually after driving for a bit, it goes from like 1,100rpm to 900ish and AFR went up a little. It happens out of the blue. It could be idling at a traffic light, or just cruising. It will just misfire for a short while, like 2 to 3 seconds and then it goes off and everything would be back to normal.

I've changed new spark plugs, new coilpacks, checked the injectors resistance. I've also sent a datalog to my tuner which he didn't see anything that was off.

Could a faulty CAS cause this?
