ISSUE:
A rough idle on vehicles equipped with Electronic Fuel Injection (EFI) may be caused by loose electrical terminals in the fuel injector
hardshell connectors.
ACTION:
To correct this, use the following diagnostic service procedure.
1.
Check each connector for loose electrical terminals.
2.
If you find that the electrical terminals are loose, remove each connector from the fuel injector and push the electrical terminals into the hardshell
connector until they are fully seated.
3.
Reinstall the connector.
4.
Pull on the wire with approximately ten (10) lbs. of force. If wire and electrical terminal pull out of the connector, a new fuel injector wire harness
assembly needs to be installed.
Use the appropriate 1987 Car or Light Truck Shop Manual for the fuel injector wire harness service installation procedure.
NOTE:
Refer to the following fuel injector wire harness application chart for the correct part application.
