I have a '97 CL 3.0 with only 97 KM. Over the last year, I have had code P0401 code come in multiple times. I reset oit a few times but now it comes on mre frequently & needs to be fixed. Spoke to the local dealer in London, Ont & they told me that 97 CLs were bad for this. Crud builds up in the intake & the EGR valves likely needs to be replaced. Acura supposedly issued a TSB & extended the warranty to 8 years or 130 KM. I talked to Acura Canada & they are evaluating whether or not they will complete the repair. I doubt they will as I am beyone the duration of the extended warranty. Not too mantion that I never go to the dealer for help due to the high $$$. If no, it sounds like a $400 bill.

Does anyone have any similar experiences or have any suggestions.

Thanks in advance.
