I had similar problems before but with my old Infiniti QX4. I had issues in and out for a few years where I also had misfires which would blow up the muffler. I would drive normal cruising on highways where it would stall. As you push the gas pedal it would not go pass a certain rpm. It turns out to be the cam angle sensor inside the distributor. I was thinking no it can't be since the the distributor was new. I checked again and also corrected the timing on it. Yeap, it did turn that it was the distributor after I replace the distributor. Ever since then, I had never had an issue again. But for the SR I would believe it would be the CAS.
