Service Engine Soon code P0401

[CrashedMax]

My engine light came on today so I went to autozone and they said it could be a clogged vacuum line. I looked it up on the net and seen its a Exhaust Gas Recirculation (EGR) flow insufficient detected. Anyone have any ideas how I can fix this. I am ordering the shop manaul on Friday. Is it okay for me to drive till I fix this?

Yes it's fine to drive. all the EGR stuff is on the intake manifold. with a couple hoses going to the charcoal canister.

So I should I replace the EGR, or could it just be a clogged vacuum line? I don't feel any difference in performance.

NO NO ....its probably just a vacuum line or something that might be clogged. Its just stuff that is for emissions. I got the same code when I put on my 1g TB because I had the lines hooked up wrong at first at the TB. Nothing to worry about, odd that you got that though with such a new car if you havn't touch the lines around it. Its located on the back of the firewall sorta right in the middle.. I would say more towards the passenger side though.
