  1. I'll check that when I get home later. That would be easier than taking apart the intake manifold.
  2. Hi, I'm new to the forum and to the GMT-400 platform. My truck is currently throwing a multiple cylinder misfire code and is running very poorly. I have already replaced the distributor, cap, rotor, spark plugs, and spark plug wires. I tested the fuel pressure and it's holding 56 PSI both with the key on and engine off and when the engine is running. The engine behaves like it has one (or more) of the poppet injectors cutting in and out intermittently. Is there any way to test the spider injector assembly before I purchase a replacement? Are the AC Delco replacements reliable units? Are there any other common issues that cause this to happen?
