Holden Apollo 1990 Problems

There are many detail differences, and I'd need to know which model Apollo you own to give you the rundown. With fuel consumption, it depends on how you drive and how well you maintain its tune, but under normal circumstances I'd expect 9.0 to 9.5 litres/100 km. The run-on could be caused by several things. I'd check the engine tune and make sure the idle and the ignition timing are set correctly.
