What makes this problem better or worse?
Doesn't do it until the engine gets warm

Hello, basic engine performance testing will be required - including checking base engine compression (with 293,000 miles -- there definitely could be base engine compression loss), engine timing, ignition spark delivery, fuel delivery, proper air intake and exhaust flow. It's entirely impossible to guess at anything without analyzing and troubleshooting the concerns hands-on.
