Check engine light came on the other day. This is the code when I vag it. It looks like its something to do with vacuum lines? Any ideas on where to start on troubleshooting this issue? I cleared the check engine light on Monday and it hasnt came back on yet - fyi

This means your passenger side EGR valve is not opening fully (or at all). Check (and replace) the vacuum hoses leading from the sec. inj. solenoid (it's the one on shelf above the throttle body on the passenger side) to the passenger side egr valve (at the back of the head). If after that you still get the error your valve might be stuck and you might have to replace it. It's a fairly easy job, although kinda hard to get to.
Alternatively, if you're adventurous and depending on your state emission inspection standards, you might be able to completely remove the whole sec. air system, the pump, the lines and the valves

The CEL didn't come up after reset for like week and a half. Mechanic replaced a air pressure (maybe blow-out) valve ( some little cheap ****) and I never had any problems.
