Boost Problem
I have a 1993 Rx 7...I had it for quite awhile and never had any problems with it. Just recently I noticed that when I drive the car normally, meaning not getting on it the turbos work just fine...however if it get on it hard and tach 2nd gear hard then to 3rd, I get no boost. If let off of it then its fine or swithc to a higher gear. It only happens when I get on the car hard...Also I've noticed a rattle underneath the car that I never had before either..Plese Help......

Do you have a boost gauge? I can't imagine getting no boost after that, but i can see low boost. I'm having a similar problem so maybe we can diagnose together.

Yep, if you can do the boost test:

that will help in providing information as to where to start looking for your problem.
If you don't have a boost gauge, now is a prime time to get one.
