A summer traffic jam really seems to put the fan/engine tin engineering to the test. I have a condition right now which I believe is a faulty Cylinder Head Temperature Sensor and it will run rough and actually shut down like a rev limiter and stall at RPM's above 3K after I've stopped at several long traffic lights, but if I go on a different sort of drive....long highways with no stops....it runs perfectly at all RPM's with the gauge reading the same approximate OIL temperature. I'm supposing that the fresh air flowing over the cylinder heads is the difference by lowering the Cylinder head temp ( again pointing to the CHT) Here's my question: This lead me to think about the fact that most 911's are in California, (and I've actually been in hot weather LA traffic jams myself as well those in as Phoenix, Las Vegas) and I've got to think that this must be absolute murder for these engines.....or am I wrong here...are they built for that?
