So I've done some good reading online and this seems to be common but has me stumped. I recently bought the car with the check engine light on and a rough idle. It has thrown both p2004 and p2008 intermittently. One of the solenoids was bad, so I replaced it and the actuator that opens the runners began working properly. Goes down upon start up and comes up with revs. However, the codes didn't go away. I have checked both solenoids for voltage and am getting about 14.2v. They both have continuity leading me to believe they are working correct. I have tested the vacuum lines using a vacuum pump like for doing brake lines. I assume the two wire plugs one is power and one is just ground? As I only get voltage to one wire on each. I have removed the intake, inspected for cracks/leaks, cleaned runners and replaced gasket but seemed to make no change. I am unsure as to what else could be causing this issue. Anything to test or try would be appreciated. Thanks.
have the same problem?
