Wedged -
He does seem to running "too cool" IMHO... and ECU's use ECT (engine coolant temp) for a LOT of control of fueling etc... So, too cold could cause him some 'errant' issues.
Thermostats don't usually fail "open" unless he has that type.. there is a type that fails open. I'm wondering if his thermostat is running within it's operating range... i.e., 175 degrees actual reading for a 180 thermostat seems within range? But I do think it's a bit cool for the application....
RICH -- Nice storage place by the way. I keep rubber hose there all the time... it keeps it soft and pliable - well - until it's been heat cycled a few times - then it can get dried up and a bit brittle. <grin>
