Hi i own a Daihatsu Hijet Pick up 1995 1ltr and i need some advise! i am not that machinicly minded but not engine thick either. it starts lovely runs lovely in dry weather how ever when the weather is damp or raining there is a problem, again it starts lovely and runs lovely until 5 mins into the trip and it starts to mis fire and runs really rough! was wondering if spray water was causing a few issues would love any advise asap really! love that little truck!
Sounds like bad plug wires or cap. If it was me I would just replace cap rotor, wires and plugs. You could use spray bottle to spray the wires see if the issues comes back. 1 liter engine me so jealous
