i have a 1994 b4000 mazda p/u 4x4 w/4.0 motor,my question is this,my transmission wont upshift after it gets warmed up,i can make it shift by letting off the gas,i also have a problem of the engine cutting out at about 4000 rpm,could thsese problems be computer related or are they separate problems?
