help

:screwy:my 99 chevy blazer does not want to start when the motor sits for a while and cools down and when it does it runs irate for roughly 20 minutes but straightens itself out.

First off, welcome to AF!

I offer two notes:

1) Your title should be more descriptive to help people that are reading more quickly determine if they can help.

2) Since your question is for a specific vehicle, it should be posted in the appropriate vehicle's forum. That way those that are experienced with that vehicle can help.
