Difficulties Difficulties with starting a cold engine. Starting the engine when engine is warmish or warm, idle rpm immediately immediately is 1200 - 3000 rpm. RPM at idle is irregular. With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm. With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C. Bad acceleration during warming up. Diesel: an indication indication is extreme extreme long time time burning time of of the glow indication indication light. •
