Hi,
I was wondering if anyone could give me a few ideas about what this could be. I'm not a mechanic and I thought I would ask some experts.
When I crank my 1999 silverado in cold weather it's fairly noisy (not the piston slap) and when I back up it almost goes dead. When I first put it in drive it almost goes dead but once I get going it's fine all day. Other than that the engine runs perfectly. It's extremely quiet.
Can anyone offer any suggestions as to what might be causing this.
