So Fix it

The engine in your General Motors vehicle depends on precision timing and accuracy. The Opti-Spark is an ignition distributor used by GM that employs an optical sensor to trigger the firing of spark plugs. Although they are known for high performance, these devices can have increased susceptibility to wear and tear and may need to be changed more often than other types of distributor caps.

Instructions

Check your local GM dealership or authorized mechanic. They will have the part in stock or can order it for you and offer services for installation.

2

Search online for "buy GM optispark." This will give you the widest range of Opti-Spark designs and types from which to choose. Also try auction sites such as eBay or check several of the large companies that make Opti-Sparks for both standard and custom use.

Contact the retailer you have chosen and ensure that the part you are buying is correct for your vehicle. You will need to supply the make, model and year of your car.

The tire pressure monitoring system on a 2005 General Motors truck consists of four tire sensors, a radio frequency receiver, and a number of modules that work together including the BCM, PCM, and passenger door module, or PDM. The tire monitoring system is activated by default, but whenever the PDM is replaced the Tech 2 scan tool must be used to enable the tire pressure monitoring system. The Tech 2 is GMs factory scan tool, and it is also the only scan tool that can re-activate the TPM system.
