We Are Now Celebrating Our

June 1st, Jeno's is changing their hours to 8am-5pm Monday through Friday


Either lit or flashing “check engine light” or “service engine soon” light will tell you its time to schedule an appointment at Jeno’s. Our auto service diagnostic testing and system analysis are thorough. We have the most updated software to handle any manufacture’s data and entire system information. We keep this current with consistent manufacture’s updates.

When you get an engine warning light, vehicles store those codes in the vehicles computers. We will perform a diagnostic code scan and through analyzing these codes, will be able to precisely determine the cause or issue resulting in the warning in your vehicle. From there, we will be able to recommend the appropriate fix and will tell you the cost estimate to resolve the issue.
