The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Common on this vehicle:Gauge or instrument faultNoiseWarning lightCorrosion or rustLeakReduced brakingAir conditioning or heaterVibration or shudder

Record by record

31 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Component named as the cause

Work done

How it is said to have ended

  • says it came back1
  • result not stated3

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

      What the documents say to do

      Passlock theft deterrent: starts then stalls / no-start with security lamp

      Confirm

      • A security lamp flashing after an attempted start means the fuel disable command is active.

      Repair

      • The condition is the Security lamp illuminated on the instrument panel, engine stalls or no start, with DTC B2960 (Security System Sensor Data Incorrect but Valid) set; the correction is to inspect and repair the cause of DTC B2960.

      Caution

      • Loss of Ignition 1 voltage to the BCM gives the same start-then-stall behaviour.

    Fuel Injection Cleaner Kit Service Bulletin

    1. 1Fault

      • Rough idle, crank no start, extended crank or misfire, with the engine warning lamp on and DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 or P0308 set.
      • When the engine is cold, compression on multiple cylinders may be zero.
      • The engine may pop through the intake or exhaust while cranking, and the spark plugs may be fuel fouled.

    2. 2Finding the cause

      Possible causes

      • Major carbon build-up on the intake and/or exhaust valves from fuel contamination or incomplete burning of the fuel; misfires should not appear before at least 8,000 km (5,000 mi).

    3. 3Correction

      Repair

      1. If there is no valve damage and no cam follower out of place, perform the cleaning procedure to free sticking valves and remove carbon from the valves and pistons.
      2. If valves are damaged or cam followers are out of place, make the engine mechanical repairs first and then perform the cleaning procedure to prevent a return.
      3. Fill Cleaner Kit J-35800-A with about 650 ml (22 oz, 2 cans) of Air Intake, Combustion Chamber Cleaner and set the air pressure at the tool to 260 kPa (40 psi).
      4. With GDS 2 or a scan tool, command engine idle to 2000 rpm so the engine does not stall.
      5. With the engine at operating temperature in a well-ventilated area, slowly and carefully induce the cleaner into the engine, taking about 3 minutes.

      Parts

      • The Top Engine Cleaning Kit (ACDelco Air Intake, Valve and Combustion Chamber Cleaner and ACDelco Fuel System Cleaner 44K) is 19435372 for the U.S. and Canada.

Aftermarket equivalents are not checked here (the links only search by number). Confirm the fit for the vehicle (VIN) before ordering.

      Caution

      • Inducing too much cleaner at too low an RPM, or stalling the engine with too much cleaner at once, may hydro-lock the engine and bend a connecting rod.

    Engine Misfire and Rough Idle Malfunction Indicator Lamp

    1. 1Fault

      • Customers may complain of a MIL and/or engine misfire, rough idle, extended crank, or crank no start.
      • One or more misfire codes (DTC P0300-P0308) are found stored in the ECM.

    2. 2Finding the cause

      Possible causes

      • The condition may result from major carbon build up on the intake and/or exhaust valves due to fuel contamination or incomplete burning of the fuel.

      Steps to confirm (in the document’s order)

      1. With the engine cold, compression on multiple cylinders may read 0 PSI (= 0 kPa).
      2. The engine may pop through the intake or exhaust while cranking, and the spark plugs may be fuel fouled.

    3. 3Correction

      Repair

      1. If there is valve damage or cam followers are out of place, make the mechanical repairs first, then perform the cleaning procedure to keep the concern from returning.
      2. With the engine at operating temperature, slowly induce a bottle of GM Upper Engine and Fuel Injection Cleaner with RPM held above idle so the engine does not stall (typically around 2,000 RPM).
      3. Turn the engine off and let the cleaner soak for 2.5 to 3 hours.
      4. To complete the repair, change the engine oil and filter.

      Parts

      • Upper Engine and Fuel Injector Cleaner is P/N 88861803 (in Canada, P/N 88861804).
