Hi I have an 86 5.0 in my mazda b4000 truck with an 83 aod. I am getting the code 67 and thinking it could be the problem of my idling issues. Does anyone know how to get rid of it? What I don't get is when I try to start my truck in drive it won't start yet I still get the code. Where would the switch be located? Also what color wire would the wire connected to pin 30 be? Could I ground this out to check on the idling issues and get codes? Thanks!
