well a few thinks:

1. Learn to write / type in an intelligent manner. Type out words completely and use full sentence structure. We are not 12 year old girls texting each other.
2. Yes it sounds like you have issues:
1. champagne test - search and or look on youtube
2. coolant pressure test
3. test coolant for hydro carbons

Do you see any leaks? Are you losing coolant? Does the car start up fine? What about after its warm?

It would also help to know where you are located so you can be pointed to a rx7 specialist to help you out.
