Important
All IAC valves on TBI Model 220 units (except those
on the 7.4L engine) are thread-mounted and have a
dual-taper pintle. On the 7.4L engine, the IAC valve is
flange-m ounted and has a dual-tape r pintle. Any
replacement of an IAC valve must have the correct part
number, with the appropriate pintle taper, for proper
seating of the valve in the throttle body.
Remove or Disconnect (Figure 2)
