[me and my metro]

Back in the mid 80s I drove a B210 with a 1.3L and a 5 speed. The little car was efficient and got 42-43 mpg in the warmer months. In the winter in Central Oregon the air blowing through the grill would cool the engine to the point that the choke would start to close. The thermostat worked fine but the heater would cool the engine. Probably a grill block would have helped. I solved the choke problem by removing the temp control on the air cleaner and running the car on hot air off the exhaust manifold. The heater would still cool off the coolant but I could put the car in 4th gear for a while and it would warm back up.
