I've been wrestling with a code 332 (EGR not fully opening) for a while now. I've replaced the EGR valve, position sensor, EGR solenoid and the vacuum lines. Not much left to replace, right? Whereas the CEL would come on as soon as the car warmed up before, now it sometimes comes on, then goes off, or doesn't come on at all or sometimes comes on and stays on. Nothing seems to be consistent. I pulled the vacuum lines today and put weatherstrip adhesive to seal the hose to nipple connections, but that did not change anything

any ideas where I should look next?
