Hi Mike.
You have 2 issues, and you really need to get the growl issue checked ASAP. What your noise is, is probably a bad water pump. I change them daily. Just did one this morning. The water pump is driven by the timing belt. If the pump locks up, you will ruin the belt, and the car will not restart. Get it checked, replace the pump.
On the P-0401, you have a blockage in the EGR valve, or the tube going to it is carboned up. This is another common issue.
Please let me know about the pump.
A FixYa rating for my assistance would be greatly aappreciated.
Thnaks in advance.

sounds to me like its a cv joint. if the rubber boot gets damaged in any way, dirt gets in there and really does some damage. check the boot really good. if you dont see any holes or anything it might just be the wheel bearing. id take it to a mechanic and ask him to just look at it. usually they wont charge ya.

On the studs on the bottom be sure to soak them with a good penitrating oil over night. Then on the removal if you feel like they are binding work them back and forth. They may break but you should get new studs with the new one. On the head side just be carefull, if you break a bolt off in the head you have real problems then. Not really complex just use your head and don't be to forcefull.
Good Luck

Had my y-pipe replaced (bad cats) and the bolts at the y-pipe flange where it attaches to the exhaust manifolds started to get loose and I go tthe viberating (tinning) noise. Took it in the first time and they tightened everything up but it seems it's doing it again so I'm going to try to fix on my own. Just wondering how much of a pain it's going to be to get to the bolts and what size...
