Replace or clean EGR?
 

2001 EX-V6 Accord with 170,000 miles. Just got a P0401 code. The check
engine light went out on it's own (TCS light was also on when this occurred)
then lit up again a week later.

Trying to find information on the procedure for cleaning the EGR. Not much
out there. Found 1 article stating special tools are required.

Anybody attempt this with the standard tools one might find in a typical
home garage? Trying to determine if I should attempt this myself or just
buy a new EGR. They're expensive ($200 plus) but maybe not depending on how
much effort it takes to clean and drill it out and what the special reamer
costs, especially if I'm only going to use it one.

Any insight from those experienced in this would be appreciated.
