I have a Honda 2000 Odyssey LX with 115,000 miles.
Check engine light came on for EGR valve and catalytic converter (checked codes for free at Autozone). I got a quote for $1,600 to repair both from the local repair shop. I told the mechanic I was going to think about it, and when I picked up the car he accidentally left in the EGR repair instructions (from an on-line service).
Using the instruction, I took off the intake manifold, cleaned it out (the the EGR intake port was clogged) and installed a new EGR valve. I took it back to Autozone to have them review the check engine light, only the Catalytic converter code remained. I then let the tank go down to almost empty, put in half a tank of the super premium gas, cleared the check engine light (pull the fuse for your interior clock - it's on the same circuit - or take off negative battery cable) and the check engine light stayed off about 800 miles, long enough for me to pass the State of Il emissions test. (I tried the super premium gas test again and it works for around 800-1000 miles.)
The check engine light has come back on again, but I have two years before the next emissions test where I will try the super premium gas routine again.
I hope this helps.
Would you buy another car from this manufacturer? Don't Know
