Smile Issues earlier CM870
Wanted to get some opinions on what could be my issue. I have awful fuel mileage, surging, rough idle, but only when cold, motor stops pulling at 1700rpm, and my turbo always sounds like it’s building boost. I’ve done a lot of reading, and all my reading brings me back to one thing, turbo actuator. I have an older CM870, and I don’t think it will throw any codes for the actuator always being closed. I just replaced the CAC and don’t have any boost leaks. TIA.
