I could just turn it off too. When your "check engine" light comes on do you just put tape over it or find out what is causing it?
It was just a suggestion. My newest car is from 1977 so I don´t have a"check engine" light ......
But as a custom car builder since 1975 I know what a Oil Pressure lamp is
Tap Tempo lamp is not a warning lamp for something faulty inside the KPA
it just behaves "faulty" by itself, and it has been discussed several times
here in the forum for years .....
Cheers !
