Yea I’m gonna replace with dealer parts I just priced them. I plan on drive through winter then in spring definitely replace. I’m have been trying to think if I did anything to contribute. I did spray Crc valve cleaner through the throttle body and ran chevron through gas tank every so often. Over the years I also put marine Ashless 2-stroke every once in a while during winter. 1 oz 5 gallons couple times a winter.
have always done this in my previous gas, diesel, small engine without a problem,
I may unscrew the upper 02 sensor and experiment with brake cleaner soaking the honey comb down. I’m gonna decon it!
there is an epic thread over a 10 year period on bob the oil guy about marine ashless 2-stroke running in gas engines it’s an interesting read but it may very well have cause problems with my cats
