Vehicles which exhibit hesitation, detonation, or rough idle (black smoke/loading) can be serviced by correcting a kinked vacuum hose to the MAP sensor.
1. Locate Manifold Absolute Pressure sensor (MAP), mounted on the front of the left hand shock tower (driver side).
2. Disconnect the manifold vacuum supply hose (90~ pre-formed) routed from the MAP sensor to the 90~ elbow, approximately 5.0" from MAP sensor. Remove the 90~ elbow and the pre-formed hose and discard.
Figure 3:
3. Obtain a 6.0" x 7/32" vacuum hose, D0PZ- 12226-C, and install a 1/4" x 1/4" straight connector (part no. 383005-S) and as an assembly, attach the connector end to the manifold vacuum supply hose and the other end to the MAP sensor (Figure 3). Verify the revised routing is not kinked upon completion.
