So I’ll start truck in the morning and let it idle for a few. Then i start hearing this tick/ rattle something like a solenoid going crazy. I cant quite figure out what it is. At idle I get close to turbo and it’s louder. Haven’t disconnected the plug yet on turbo. Doing that next. I have noticed that getting on highway mild peddle when it shifts I got a turbo bark couple times. Factory turbo with 250,000 miles. Cold air filter clean. Has anyone had this issue with turbo? What should I do? I’m going to upgrade turbo soon but need this one to still work fine for spare parts. Thoughts?
