| "Unplugging the solenoid connector kept the ECU from interferring with EGR function. Idle will still be smooth as no vacuum goes to EGR with throttle closed." "Blipping the throttle on my thottle yielded vacuum to the valve also, but with the solenoid connector attached vacuum only occurs for a second or two, whereas when I disconnectd the electrical connector vacuum continues when throttle is open." Isn't the solenoid only supposed to open for one or two seconds? Also, how does an unplugged solenoid still block the vacuum when the throttle is closed and at the same time stay open at the same time?
