2013 Accord w/ 145k miles on it. Last timing job in 2020 at 100k with all Aisin parts. Went to leave for work yesterday morning and had a severe misfire on start up with P0300/301/302/303 dtc’s. All bank 1. Even threw a “FCW failure” across the dash (unrelated). Just had a chance to look at the belt and it jumped 3 teeth on bank 1. Belt looks perfect. Im guessing its stretched excessively since I had no prior symptoms of a failing tensioner. I’ll find out more next week when I get the lower cover off and replace everything. Could be a bleeding tensioner. Read on several other Honda forums of this happening with Aisin stuff as well as direct Honda parts. So Im just going to make up my own kit I guess. A mix of Bando, Continental and Gates maybe. I dunno. Very disappointing. The only symptom I had was a slight skip on startup when cold. But its done that for the longest. Now Im thinking the cam was progressively becoming -out of time- from a stretched belt and the tensioner maxed out when it jumped. Bank 1 cam is just along for the ride and depends solely on the tensioner to maintain correcting positioning. Think I’ll steer clear of all Aisin parts this time around and see what happens.
