check engine light on when i clear code truck runs better like its lost power sounds rough could cats be clogged
Do not clear the codes. Get the code numbers and post them here. Then we may be able to offer some advice.
Please post engine, transmission, drive configuration, mileage, and maintenance history.

Concur w/above advice , post the retrieved diagnostic codes for best help here. Clearing a code will sometimes change the computer to a monitoring state where it will use default drivetrain while it checks for other problems. Maybe that is why your truck seems to run better after clearing the code… Clearing the code however is at best a short term fix. The “runs better after clearing code” symptom btw doesn’t seem consistent w/a clogged cat.
