So heres my problem.. CEL came on.. P2006, P2007 came up. Alldata says "Intake Manifold Runner Stuck Closed bank 1 (P2006) and bank 2 (P2007)" It comes on, then goes off, comes on.. Goes off.. (Every few trips.)
Friends say its a vacuum leak. TSB says it could be a vacuum leak or the intake manifold actuator diaphragm. My other friend gave me a vacuum pump to use saying i could use it to diagnose this. I have never worked with vacuum lines before, could some give me some directions? Has anyone experienced this?
