  It could be many things, unfortunately and without being able to do some basic diagnostic tests its hard to say. Lean on bank two I would look for a vacuum leak, a vacuum hose damaged or off or bad intake manifold gasket on bank two. Another possible cause would be a failing fuel injector causing a lean mixture but that would likely set a code identifying a particular cylinder misfiring.Bank two is the driver's side of the engine.

• fuel smell after servicing
  I have a 5.4 Triton SuperCrew Lariat 4x4 F150 with 96000 miles - just did the 100000 which included plug change. Now I have a very strong fuel smell - especially at idle. My guess is a loose plug...

• Does the Lariat have a delta pressure feedback (DPFE) sensor? If so, where
  Cannopt find the dpfe. Where is it located?
