Thanks folks for the response. I got 227k on original injectors no smoke yet. Good compression, afaik. The engine has been HIGHLY maintained. Synthetic oil changes every 3k and fuel filters every 6k miles.

Jay Bob, I will be in touch with you this spring. I’d like to wait til we get out of this 20 degree weather in pa. I really miss having my lift at Mercedes with a heated shop. But career paths changed.
