Suburban. Tuned up and drove like a champ to Arizona and back to Oregon again after 30 days.
Ran and drove great until one day she started gasping, choking and shaking like crazy!! I drove her 3 miles to
a safe place to stop.
When I fire her up cold (choke) she runs and idles as she should. As she warms she begins to choke up and shimmy.
I have had no issues until that day, and I have noticed when I turn the engine over, the starter and flywheel are having trouble.
Any ideas? I have taken care of my truck and had everything replaced as necessary throughout time. I realize mileage has
a part in it, but I really feel this can be resolved because all was well, and then it wasn't but I don't know enough about
the bottom end. I do not have a mechanic in my new home, so seeking thoughts from experienced people.

 

Motor mounts?
