1. Use a scan tool to monitor the fuel trim numbers and the Mass Air Flow (MAF) sensor data stream grams/sec readings. Nominal
values are 5 grams/sec at idle in Park, and >150 at Wide Open Throttle (WOT) and 5000 RPM, in gear. Some scan tools have a freeze frame feature, which is useful in trouble shooting if the problem is set at idle versus at cruise. Vacuum leaks and crankcase breather problems generally show up at idle. Voltage at the airflow meter should be .7-.9V at idle and increase from there with more airflow. 2. Monitor the crankcase vacuum with a vacuum gauge, which can be adapted onto the tube for the oil dipstick. Specification for the crank case vacuum is 8 to 15 millibar, this equals about 1/4 to 1/2 PSI or pounds per square. So, 1 PSI of vacuum would be twice as much as there should be at idle. The proper method, per BMW, is to use a slack tube manometer which can be made easily with clear tubing and making it into a U shape and have it marked in inch increments then half fill it with water. When crankcase vacuum is applied to one side of the tubing it should displace 4 to 6 inches of water if the crankcase breather is working correctly. 3. Monitor the fuel pressure. It should be a constant 50 – 53 PSI.

Cause This condition may be caused by a damaged forward sprag assembly (642). Correction When inspecting the sprag, it is important to test the sprag for proper operation by holding the outer race (644) with one hand while rotating the input sun gear (640) with the other hand. The sun gear should rotate only in the counterclockwise direction with the input sun gear facing upward. If the sprag rotates in both directions or will not rotate in either direction, the sprag elements should be inspected by removing one of the sprag reserved. retaining rings (643).

Be sure to use correct repair procedure. The water pump on 2001-2006 Tribute vehicles built BEFORE Jan. 17, 2006 are driven by the “INTAKE” camshaft pulley. 1. Verify the water pump is driven by the INTAKE camshaft pulley. 1572g WATER PUMP DRIVEN BY INTAKE CAMSHAFT PULLEY

FOLLOW THIS TSB PROCEDURE ONLY IF THERE ARE NO SPECIFIC MISFIRE TSBs/SSMs RELEASED FOR THE VEHICLE SYMPTOM BEING
EXPERIENCED. ISSUEnApproximately 50% of coil on plug (COP) coils returned for warranty do not have a problem.
ACTION The misfiring cylinder must be identified through Self-Test misfire codes or through WDS Power Balance. Rule out base engine problems, rule out fuel problems, and then look at ignition problems (be sure to rule out coil primary circuit issues).
Once the above steps have been completed, and the issue is in the secondary part of the ignition system, the oscilloscope procedure outlined in this TSB can isolate the difference between a coil or spark plug problem.
