A quick search would have answered your question hours ago, but here is a short list:


1- top off coolant

2- heater core check valve near firewall in engine compartment.

3- Would you like to see a pic of where it is? do a search!

Have you checked your vac lines from the plenum to the VSV? I had a similar problem in mine, I found out it was my vac line from the plenum to the VSV wasn't connected after a dyno run! Also check your VSV as well as it could be stuck.
