estimated time of repair and rate of difficulty
tune up on 1999 Mazda B2500
In order to do all the wires and plugs, it takes about 2 hours, because on a 4 cylinder, there are 2 wires and 2 plugs for each cylinder, due to Emissions. The fuel filter takes about 1/2 hours and the air filter is pretty simple as well. I would grade this as a 5 on a 1-10 scale.
