Default Need Help...

Just had a service engine soon light appear after driving my 95 auto coupe about 20-30 minutes. Slight ticking coming from the passenger side valve cover/intake manifold area Noise is barely noticeable and sounds like it it coming from the rear of the engine. Any suggestions or anyone been down this road and have advice to give? Just had Exhaust done no rear res (replaced with x) Spintech 9000 series mufflers 3inch in 3inch out. Mayby that could be a contributing factor?

Default svc light

When the 'svc. eng. light' appears, it means that a sensor has detected a malfunction, and a trouble code (DTC) has been set. You need to determine what code has been set by attaching a code reader to the diagnostic link under the dash.
