Hello, what testing has been performed? Are there any warning lights on? Any diagnostic trouble codes present in the processors that can be helpful for troubleshooting? If there is a misfire, it will show up. Base engine concerns such as valvetrain issues, compression issues can be determined via compression tests and cylinder leak down tests. These concerns may not show misfire codes in some cases. Hands on testing is needed, regardless. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
