The plugs in the Hiace are BP5ES.
That the right heat range for them? I'm trying to find the cause of the run on problem. Checked the idle and its not idling high, and it's not gas related ( does it on 91,96 and 98 ).
Could you let me know if thats the right plug range or not, and if not, what should it be.
It's an 87 with a 3Y.
