Re: 2000 4.6 with auto expidition skipping bad
You should be able to find what cylinders are missing. With the newer systems, certain problems turn other systems off for emmision reduction and they don't run with as much power. If it was missing for awhile, it may also cause a cat to plug up.
Schrader valve should be passengers side on the fuel rail. Fuel pressure should be 30-45psi key on engine off.
