Does have the 2006 E-350 a IGNITION CONTROL MODULE?
 

Im wondering if my E-350 needs/uses a ICM?

There is a 'Dual Curve Ignition Start Control' (Autotoronic Co.) in a bracket beside the intake air cleaner housing. And I'm wondering if it is needed.? Please help me. Me van lacks power and sometimes stall while parking outside WHEREVER. Seems like somebody ADDED that part. Help me please.
