Chevrolet Dealer Service Bulletin 87-109 (Section 6E) dated April, 1987 is being reissued to add 1987 Celebrity models to the Minimum Idle Speed
chart. All copies of 87-109 dated April, 1987 should be destroyed.
Some 1985, 86 and 87 vehicles equipped with 2.8L V-6 P.F.I. engines may experience a stall after start with a warmed up engine or a stall during
deceleration.
This condition may be caused by residue accumulating inside the throttle body bore behind the throttle plate and limiting air flow past the throttle plate in
the idle position.
To diagnose this condition, perform the following steps:
1.
Measure minimum idle speed using procedures defined in Section 6E3 of the service manual.
2.
If the minimum idle speed is less than what is specified below in the minimum idle speed chart, proceed to Step
3.
Otherwise, perform activities defined in the service manual under Section 6E3, Section B - Rough, Unstable or Incorrect Idle, Stalling.
