SYMPTOM/CONDITION
A condition may exist on certain subject model vehicles of long crank times (3-6 seconds) and rough idle after a hot soak restart.
The rough idle lasts about 1/2 to 1-1/2 minutes after a 10 to 20 minute engine-off hot soak (preceded by a 15 to 60 minute drive at highway speeds). This
condition is the result of the fuel injector housing contacting the intake manifold.
NOTE:
This service applies to 1985 2.2L turbocharged vehicles with engine build date prior to 1-145.
The engine build date label is found on the left (driver's side) rear surface of the cam cover below the throttle cable. The engine
build date is the upper set of numbers (i.e., 1-145).
DIAGNOSIS
Fuel injector housing to intake manifold contact can be determined by the following procedures:
With fuel rail assembly still installed in the intake manifold, hold injector at wiring terminal and rotate it in the intake bore. The injector, once loosened
up, should rotate freely.
If injector is difficult to rotate, injector housing to intake manifold contact can be suspected. This procedure should be repeated for the remaining three
injectors.
