FOUND: Connected a scan tool and found code P2096 – Post Catalyst Fuel Trim System Too Lean (Bank 1). Performed a road test while monitoring live scan tool data and observed the oxygen sensor (B1-S2) parameter was below specifications and did not respond to changes in air fuel ratio. Inspected the oxygen sensor (B1-S2) wiring harness and detected no obvious faults. Performed a propane enrichment test at idle, monitored the oxygen sensor (B1-S2) signal parameter on the scan tool and found the sensor signal parameter did not respond to the rich fuel mixture condition. These test results verified the oxygen sensor (B1-S2) was faulty. Suggest R&R O2 sensor B1S2 while test drive found minor misfires under no load and proceed to pull the spark plugs in the passenger side, found 2 of the spark plugs hand tightened. spark plugs electrode looks OK but are being expose to the compression from the engine, same problem with the 2 coils packs are in bad shape due the compression leak(oil a the junction of the coil pack). also the combustion chambers(1,3,5) was bore scope and found in normal conditions. Suggest R&R 6 spark plugs and 6 coil packs. Car cooling system was pressure tested found small leaks from loosen hose clamps. clamps where adjusted and the leak went away.

FOUND: verified concern, found a cylinder misfire in cylinder 2 and fault codes stored for misfires in cylinder 2. moved ignition coils from2 to 4 and misfire moved with ignition coil, verified ignition coil is faulty. inspected spark plugs and found them to be worn excessively, recommend replacing all spark plugs and coils to address concern.
SPARK PLUGS – Remove & Replace – All
INCLUDES REPLACING BRAKE PADS, REPLACING OR RESURFACE ROTORS, CLEAN, ADJUST AND ROAD TEST.
