Services Performed
- Verified smoke from tailpipe on acceleration. Checked engine coolant level. Coolant is full. Attached engine block tester to cooling system reservoir. Block test passed. Recommend replacing PCV due to symptom and high frequency failure. PCV is not accessible unless intake manifold is removed, which requires engine removal. Check engine light is on. Scanned engine control module for codes. Found current codes P0139 (oxygen sensor 2 slow response), P0303 Misfire on cylinder #3), P0300 (random/multiple cylinder misfire) and P0507 (idle speed control implausible signal). Verified misfiring on cylinder #3 with scan tool data (misfired 273 times). Removed #3 ignition coil. Coil is saturated in engine oil due to valve cover spark plug tube seal leak. Recommend replacing spark plugs, ignition coils, valve cover gasket and tube seals.
