1995 S10 Blazer 4.3L 107K. The Autolite APP25 spark Plugs are fouling out within 5K miles. When I removed the plugs they were all very black, but not wet like oil. So after reading some of the posts it seems that the fuel filter and pressure regualtor should be replaced. I just installed new Distributor Cap and Rotor, Spark plug wires(all were original), and another set of Autolite APP25 plugs. My question is this. Has anyone replaced the pressure regualtor on this car for the same problem? If so did it solve it? How difficult is it to replace the regulator, any tips (gaskets, seals, adj.)? Should I also clean the injectors at the same time? If so any suggestions, I've never cleaned any before? Thank in advance.
have the same problem?
