I really don’t know if it’s bad or not. How much would you charge me for the 505?If your ECM is indeed bad, I can hook you up with a good used -505 ECU for a reasonable amount. However, you should be aware that you will need to get your keys programmed to the new ECM or else it won't start because of the immobilizer.
This being said, I'm dubious that your ECM is bad. It seems more likely that either you either have a bad new EGR valve or damaged wiring.
The replacement EGR Valve that several folks have had good luck with is a WVE 4F1006 (<-- link to it on Rockauto) EGR valve. It has the proper, large port openings like the OE Honda valve. It does require bending a wire support bracket to clear the plug on the valve. Super easy.
Please try some of the suggestions in this thread before buying a new ECU! There's a lot of smart people on this forum who have lots of experience with these cars. Like retepsnikrep said, it is true that an ECU failure is extremely rare, and there are many other common failures that can give similar symptoms. As Sean suggested, please pull the connector off the EGR valve and see how it runs, and check all your ground straps. Two very easy things to try that are common problems on these cars.I really don’t know if it’s bad or not. How much would you charge me for the 505?
