[QUOTE="Thatblackraptor, post: 1894436, member: 62450"] Started to troubleshoot the IWE today after some road noise on my last road trip. Put 1500 miles on the truck and couldn’t get past the noise. Replaced the IWE actuator on drivers side a few months ago. IWE on both driver and passenger holds vacuum around 20in applied and doesn’t drop. I then applied vacuum to the system after the solenoid (testing each IWE and tubing) and it held vacuum as well so no leaks. Reading from engine side of check valve. This seems low? Only 14in of vacuum applied to check valve from intake? [ATTACH type="full" alt="A3BABE09-9CBC-4250-9147-F0704FD9D341.jpeg"]400171[/ATTACH] Drivers side reading from IWE line. Seems low at 9in of vacuum [ATTACH type="full" alt="BCA8D258-F97A-42B6-B41B-D6D06D36E2F9.jpeg"]400172[/ATTACH] Passenger side reading from IWE line. Almost 6in higher than the driver side.
