I have a 1991 E-250 with a 6 cyl 300 cu in engine and automatic transmission.
I bought it used. When I went to tune it up I found that the decal with the spark plug and timing settings was missing.
I need to know the settings or if they are specific to my individual truck, where I find the settings using the vin number.
Thanks
