Check the ECU codes. Might be a water thermo sensor or an Oxygen sensor...

Do you have a hole or leak in the exhaust? This would creat popping..

You should also check your car for leaks (especially under the upper intake manifold area). There's a common failure on RX7's with the pulsation dampner which can lead to fires (yikes!) if not taken care of. Better be safe than sorry and check!

i found out how to get the codes... and i found out that my pulsation dampener is leaking... all i need to know now is to see if i can fix the pulsation dampener without replacing it with a new one...

You should be able to order one from Mazda. Or replace it with a banjo bolt like many other people do.

Just remember that a banjo bolt doesn't do a PD's job, but makes sure it doesn't leak and cause a fire. Whichever is more important to you, you have to decide. I'd have to search and find specs.
