My 2020 RX4 has been experiencing hard starting issues all year that I haven't been able to solve. The bike has roughly 26k miles on the clock. It will usually take 3 attempts on the starter before the bike will start from cold. If you restart it immediately after shutdown it will start first try. There are no DTCs present, and the bike runs like a scolded dog once started. Maintenance wise, the bike has a fresh Oil change, Valve adjustment, spark plug, and air filter. I have changed the ECU and fuel injector (I had this issue before hand and no change). I cleaned the MAP sensor though I still will still likely order a replacement. I haven't found an easy way to access the throttle body to give it a good cleaning without removing the airbox. Any ideas?
