I have a 97 metro lsi that starts and runs when cold but once it warmed up it dies and is very hard to restart. If it does restart it will not idle.

You could have a lek in your intake manifold. Possibly... As it gets warm and the metal expands it opens it up further causing this problem. Good luck...

doug2060 Thanks for your reply. I checked with carb cleaner. I dont believe that to be the problem.

Carb cleaner will not always catch this issue. Mine did this once and after everything I tried failed including carb cleaner test I completely disassembled the intake and put it back together with new gaskets. It ran perfect afterward and since. You may also have a blown head gasket. Have you done a compression test? Does it have an EGR? Are your spark plugs good and snug... There are a few things that can cause this.

Will it looks like some work to be done when the darn snow stops.
