Understand your service
A trouble code is a starting point
A stored code identifies a condition that needs investigation; it does not automatically prove that a particular part needs replacement. Symptoms, service history and diagnostic findings need to be considered together. Sharing recent repairs or maintenance can help make that conversation more useful.
Concerns to discuss with our team
- A check-engine light or engine-related message
- Rough running, hesitation or a change in acceleration
- Difficulty starting or unexpected stalling
- New noises or changes in engine performance
Care for your vehicle
Maintenance history helps explain the bigger picture
Oil-service records and previous repair details provide context, especially for an older GM vehicle. If several concerns appeared together, describe the sequence rather than choosing a diagnosis in advance. Our Pasadena team can discuss your engine concern and any related maintenance needs without treating every warning light as the same repair.

Service Questions
View AllDo you offer engine diagnostics?
Yes. Spence & Frye GM Specialist provides engine diagnostics and repair. Trouble codes, symptoms and inspection findings help determine the next steps rather than assuming a code identifies a failed part.
Should I clear a warning code before my appointment?
Avoid clearing codes solely to switch off a warning light. Stored information can help Spence & Frye GM Specialist investigate the concern; tell us if codes have already been cleared.
