Multi player on my 1991 LS400 jumps when I drive over bumps. Does anyone know a cure? I have considered buying a second hand replacement but Iam concerned that it would be the same
Thanks for posts. Turned out to be a coil that was changed only a few month ago so I had assumed it was ok. The car is running spot on now.
I am hoping cats will be ok has I have only run the car 2 miles with them on and with dodgy coil.
1991 LS400
Car has no power and is misfiring
I have recently changed both ignition coils and the spark plugs, and have changed the cats.
Perhaps I should do the LAMBDA sensors?
