90 GXL won't idle and runs crappy

Ok I know this is a noob question. How do I check the codes on this car. I am not new to cars. I have worked on Honda, Nissan, and GMC vehicles but never a rotary mazda. So any help would be appreciated.

After a lot of digging I finally found that, but thank you anyway for the reply. I hope that they are easy fixes.

Got the code it is...11 - Intake Air Thermosensor (Engine) - Intake air fixed at 68F...wtf is that? lol

Good to hear it was an easy fix. The IAT sensor measures intake air temp, and the ECU uses this input to adjust the air/fuel mixture.
