SUBJECT:
COLD START ROUGHNESS/FAILURE TO RUN AFTER COLD START (DROP-IN MANIFOLD DEFLECTOR PLATE)


MODELS AFFECTED:
1987-1988 SKYHAWKS WITH 2.0L ENGINES (VIN CODE 1)


Customer comments of cold driveaway roughness, hesitation or failure to run after a cold start and idle may be addressed with a drop in the manifold deflector plate, service kit, P/N 10112342. This deflector prevents liquid fuel from collecting in the manifold's EGR passage which is then ingested into the engine at initial driveaway. Depending on ambient temperature, the engine needs to idle longer than one minute for this condition to occur.

Parts are expected to be available on January 9, 1989. Until then normal part orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be canceled as incorrectly ordered while the 400 control is in place.

After installation of this kit check the transmission throttle valve cable (Service Manual Section 7A1) and the cruise control cable (Section 9C) for proper adjustment.

If the subject conditions still continue, refer to the Service Manual Sections 6E2-A and B for further information.
