I have a 1990 Isuzu pick up. Whenever i am driving and clutch it it idles down and dies. if i keep my foot on the gas until i stop it does fine. when i am not moving it idles fine. the only time it goes dead is when rolling in neutral or rolling with the clutch in. can anyone help with this problem? thanks

 

You should check the clutch plate and release bearing properly. I think the problem is in that only.
