Hi Joel, nice to hear someone on their 2nd IS220.
I bought mine in 2017, no problems with injectors, but during lockdown in 2020 I had to change the battery, as it doesn't like not being used for weeks at a time. Last year it went into limp home mode, AA patrolman hit the EGR valve with a copper hammer, removed the error code and sent me on my way. I cleaned the EGR a week later, ran perfectly since.
