lntake manifold runner control (IMRC)
throttle plates
The intake manifold for both Ethanol
E85 and
standard unleaded fueled vehicles is the same
construction.
Built into the intake manifold, are the
IMRC throttle
plates and IMT swirl plates.
Under low demand throttle conditions, the air
charge is delivered to the cylinder head intake ports
through the primary air intake chambers. The clean
flow of the air charge is disturbed by the IMT swirl
plates to assist in the mixing of the air fuel mixture
at the fuel injectors.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
or electrical damage.
