Just had the 22re rebuilt in our 1986 pickup. I'm trying to locate the source of a miss and it seems to be EGR related. I'm not clear if I have the vacuum lines on correctly. I've looked at the FSM and researched the FAQ as well as searched mud for other threads showing the routing but I'm still not clear on a couple of these, especially 1 and 2 below. None of the pictures in the FSM show the Modulator Valve port labels. I can make an assumption based on the orientation of the ports on the valve but I would like to confirm the correct hookup.
Can somebody verify if I have these right?
1. 'E' on Throttle Body to 'P' on EGR Modulator valve
2. 'R' on Throttle Body to 'R' on EGR Modulator valve
3. 'Q' on Modulator valve to lower port on BVSV (located on front of Intake Manifold)
4. EGR signal port to upper port on BVSV (located on front of Intake Manifold)
5. EGR Exhaust Pressure port to Modulator Valve Diaphram (Larger vacuum line)
Again, this is a 1986 22RE California Engine. FSM Diagrams and picture of the modulator valve I'm referring to are pictured below.
