A 3.5L V6 has a single-cylinder misfire that is worst hot at idle. Scan-tool data and basic checks show relative compression flags cylinder 5 low; leak-down is 34 percent with air heard at the tailpipe. The technician also verifies fuel pressure and injector balance are normal. What is the best diagnosis or next test?
A late-model gasoline vehicle has strict catalyst monitor thresholds. Scan-tool data and basic checks show a small exhaust leak upstream of the downstream O2 sensor appears only when cold. The technician also verifies P0420 sets after cold-weather trips. What is the best diagnosis or next test?
A direct-injected engine has long crank and rail pressure slow to build. Scan-tool data and basic checks show low-side pressure is normal but high-side pressure remains far below command during cranking. The technician also verifies the high-pressure pump command is high. What is the best diagnosis or next test?
A plug-in hybrid has stale-fuel maintenance engine starts. Scan-tool data and basic checks show the engine runs even with sufficient battery charge and no engine DTCs. The technician also verifies scan data shows fuel maintenance mode active. What is the best diagnosis or next test?
A diesel displays an SCR efficiency warning. Scan-tool data and basic checks show NOx remains high downstream of the SCR catalyst and DEF quality measures below specification. The technician also verifies exhaust temperature reaches dosing enable criteria. What is the best diagnosis or next test?
