Replace your spark plugs first and see if misfires disappear.
Dealer wanted to fix my misfires by replacing injectors, i went ahead and replaced plugs myself and the issue was gone. The car was ~70K miles on original spark plugs anyway

Does anyone know if the BMW tech simply messed my car up? Because I had gone to a local mechanic before bringing to BMW because the local mechanic scanned and told me it was the HPFP. There were no other codes! Even BMW didn't get any other codes before they replaced the HPFP. And I know it would throw out codes for misfiring. I think the dealer service is trying to make money off me since they are not getting any money from me for the recall. Thanks for any input. I am also waiting for the detail diagnosis from dealer
