Hi, I'm trying to debug a misfire problem and I need some advice. I have a vacuum gauge tapped into a "T" on the vacuum line going into my fuel pressure regulator. I don't know how to perform at proper diagnostic. Any advice? At idle warm, I get 8" hg. At idle hot, I get 12" hg. At higher RPM, I get consistently 19" Hg. At low RPM (idle), the needle wavers. My tach needle also wavers. I have a misfire in one of the cylinders. Compression on cylinders 1,2,4 is 150psi. Cylinder 3 is 130psi. -- Craig |
