摘要：	Newly learned skills often allow for unobtrusive testing procedures that can allow a technician to disassemble only what's needed. An example of this application of newer testing techniques is carried out below. A 2009 Chevrolet Suburban 5.3L arrived at the shop (Figure 1). According to the repair order, the vehicle was experiencing a misfire and the MIL was illuminated. Walking out to the lot, I contemplated a plan of attack. Concerning misfire troubleshooting strategies, there's always a fork in the road. One path leads to a mechani- cal failure/cylinder wash possibility. The other encompasses all the other possibilities; air/fuel concerns, ignition, electrical, etc. Oftentimes, the injector of a misfiring cylinder is disabled, preventing cylinder wash under weak/no spark conditions.
