Cadillac, Chevrolet, GMC PCV KILLING SPARK PLUGS

This TSB applies to 2007-2011 Cadillac Escalade/Escalade ESV/Escalade EXT, 2007- 2011 Chevy Avalanche/Express/Silverado 1500/Suburban and Tahoe, and 2007-2011 GMC Savana/Sierra 1500/Sierra Denali/ Yukon/Yukon XL/Yukon Denali and Yukon Denali XL, all equipped with the Gen 4 V8 engine.

Some customers may comment on a service-engine-soon light being on and/or a rough running engine. Technicians may f nd DTC P0300 set. Upon further investigation, technicians may f nd cylinder #1 and #7 spark plugs oil fouled and/or the porcelain may be cracked or broken on the combustion chamber side.

This occurs on the left side of the engine due to PCV pullover that adds additional oil to the cylinders that can foul out or damage the spark plugs.

Install a new left valve cover with the revised baff e to prevent PCV pullover.

Nissan NISSAN SHIVERS WHEN COLD

This TSB applies to 2010-2012 Nissan Altima sedan and coupe vehicles equipped with the QR25DE four-cylinder engine with

California emissions only. The idle speed may f uctuate from approximately 1,000 to 2,000 rpm during all of the following conditions:

• Occurs for no more than one minute after the engine is started. • Only when the engine is cold. • Only when the transmission is in Park or

Neutral.

Idle speed is normal (stable) when the engine warms to normal operating temperature.

NOTE: This incident may occur immediately after an oil change.

1. Refer to Step 2 in the service procedure to conf rm that this bulletin applies to the vehicle. 2. If this bulletin applies, reprogram the

ECM.

SERVICE PROCEDURE

1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure. CAUTIONS: • Connect a battery charger to the vehicle battery. If the 12V battery voltage drops during reprogramming the ECM may be damaged. • Be sure to turn off all vehicle electrical loads to avoid ECM damage. • For ECM reprogramming, the CONSULT

PC must be connected to the VI using the

USB cable, or the process may be interrupted and the ECM may be damaged. • Be sure to connect the AC adapter. If the CONSULT PC battery voltage drops during reprogramming, the process will be interrupted and the ECM may be damaged. • Turn off all external Bluetooth devices (cell phone, etc.) within range of the CON

SULT PC and the VI. If Bluetooth signal waves are within range of the CONSULT

PC during reprogramming, reprogramming may be interrupted and the ECM may be damaged. 2. When you get to the ECM reprogramming screen shown in Figure 1, conf rm that this bulletin applies as follows: a. On your C-III screen, look at the Part Number column. If this column is blank (no part number listed), this bulletin does not apply. Close C-III and refer to ASIST for further diagnostic information. If a part number is listed, write this number down on the repair order. b. Compare the part number that you recorded to the numbers in the Current ECM Part Number column in Table A. If there is a match, this bulletin applies. Continue with the reprogramming procedure. If there are two reprogramming options on your C-III screen, use the one that does not have the message “Caution! Use only ONLY with NTBXX-XXX.”

3. If this bulletin applies and you have performed ECM reprogramming, the screen in Figure 2 will display when reprogramming is complete. If the screen in Figure 2 does not display (reprogramming does not complete), see the ECM Reprogram Interruption Recovery” general procedure. Print the screen and attach it to your work order. 4. Be sure to erase all DTCs from all systems. During reprogramming, DTCs will set in several systems and must be erased. 5. Test drive the vehicle and make sure it operates correctly and that the MIL is off.
