1993 OBS 350 TBI. When I’m in park the engine revs and idles great. When I put it in gear it starts a rough idle and feels like it’s skipping. Once I’m up into the gears (4L80E) and I try to accelerate, I hear a dinging or clanging noise almost like valve train noises. Garage guy said it was a vacuum line. He replaced one and it’s still bad. Thoughts?
