Various vehicles equipped with a 4.6L, 5.4L, 6.8L modular 3 valve engine built on or before 8\-Jan\-2016 may exhibit symptoms that may include upper end engine noise, rough running, misfire and/or engine damage. If diagnosis leads to only camshaft/camshaft roller follower\(s\) requiring replacement, replace all of the camshaft roller followers on both banks/cylinder heads with part number 3L3Z\-6564\-A, not just the faulty roller follower\(s\). When replacing the camshaft roller followers, refer to Workshop Manual \(WSM\), Section 303\-01. - [SSM 46085](/bulletins/10109070.md), 2017-08-01, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE \(EGR VALVE\); ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS; ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY; ENGINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE \(PCV\); ENGINE AND ENGINE COOLING:COOLING SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:ENGINE:DIESEL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:BELTS AND ASSOCIATED PULLEYS; ENGINE AND ENGINE COOLING:ENGINE; ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN. The Powertrain Control/Emissions Diagnosis \(PC/ED\) manual has been revised for diagnosing electronic throttle bodies \(ETBs\). The ETC\_ACT and ETC\_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes \(DTCs\) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information. - [TSB T2006\-01](/bulletins/10096425.md), 2017-03-27, Service bulletin: ENGINE AND ENGINE COOLING:COOLING SYSTEM.
