Why does my 97 firebird 3800 misfire under load with out any engine light or codes setting?
You could have a problem with exhaust back-pressure which can stem from a restricted converter. To test for this you can use an exhaust back pressure tester inserted in the upstream 02 sensor. You can also remove the upstream 02 sensor and test drive the car. There should be some improvement in the car's performance under load with the exhaust having a place to go. This will be very noisy, you will not want to run the car like this for too long.

Why does one cylinder misfire show 5 codes?
A single cylinder misfire can trigger multiple diagnostic trouble codes (DTCs) because the vehicle's engine control unit (ECU) monitors various systems and parameters. When a misfire occurs, the ECU detects issues such as fuel delivery, ignition timing, or exhaust emissions associated with that cylinder, leading to codes related to each of these systems. Additionally, the misfire can affect overall engine performance, potentially triggering codes related to broader engine operation. Thus, a single problem can cascade into several related codes being logged.
