P2187 Bank system too lean at idle, can a gas cap loose cause this code? No. You have a lean air to fuel ratio. Lean air to fuel ratio can be causes by a MAF (mass air flow) that is faulty or even a bit dirty, A MAF air flow cleaning may help, Vacuum leak can cause lean idle, Fuel pressure low or even a partial clogged injector, Above all it may be time for a tune up, worn sparkplugs do cause lean air to fuel ratio,And if you have a faulty gas cap replace it,Fumes are gasoline also.
