1984 Mercedes Benz 190E Fuel Delivery and Air Induction Engine Testing And Adjustment Manual

Note: Test and adjust lambda control with a lambda control tester. The lambda control and the idle speed emissions level must not be tested when the engine is very hot, e.g. immediately after driving sharply or after measuring engine output on the dynamometer.

Adjust fulcrum lever (13) with the connecting rod (2), if necessary, so that the roller (15) is resting free of tension against end stop. 11 Idle stop. Check whether the throttle valve is resting against idle stop. Disconnect connecting rod (2) for this step. Adjust throttle control. Engines with cruise control only. Check whether the actuator is resting against idle stop of cruise control by pressing the lever of the actuator clockwise against idle stop at cruise control. When attaching the connecting rod (21), ensure that the lever of the actuator is lifted approx. 1 mm off the idle stop at the cruise control. Adjust tie rod, if necessary. Adjust throttle control. 12 Check wide open throttle stop from the accelerator pedal , adjust. 13 Voltages Test (battery and ignition coil ): No-load voltage Connect voltmeter to the battery, paying attention to the polarity, and take reading of voltage.

1997-1998 Buick Regal GS & Pontiac Grand Prix GTP with L67 3.8L V6 Engine Fuel Pump Resistor Service Procedure

The following are instructions for removing the fuel pump resistor from its original mounting location on the lower right front body rail as shown in Figure 1, and replacing it with a new fuel pump resistor and cover in new location shown in Figure 2. The new location is on the front of dash sheet metal (3) at the rear of the engine compartment, inboard or to the left of the alternator (4). The passenger or right side windshield wiper arm (5) and stop (6) are called out for reference purposed only. 1. Turn the steering wheel to the full right position. 2. Open the hood and disconnect the negative battery cable. 3. Remove the diagonal brace (1) from over the windshield washer solvent reservoir by removing the two bolts (2) that attach it to the radiator support and the one bolt (3) that attaches it to the strut tower. Refer to Figure 3 4. Remove the two plastic push-in retainers (1) that attach the windshield washer solvent reservoir (2) to the radiator support (3) and the one nut (4) that attaches it to the strut tower (5). Refer to Figure 4. 5. Reposition the reservoir for access to the area rearward of the battery. 6. Raise the vehicle on a hoist. 7. At the right front wheel opening, remove the three screws that attach the inner fender splash shield to the front fascia at the wheel opening and the two screws that attach it to the bottom of the fascia. Refer to Figure 5. 8. Reposition the inner fender splash shield (1) to access the fuel pump resistor (2). Refer to Figure 1 at the beginning of this procedure. 9. Unclip the fuel pump resistor electrical connector from the body and disconnect the connector. 10. Remove the 10mm hex head bolt attaching the fuel pump resistor to the body and discard both the bolt and the resistor.


HIGH TENSION WIRE RESISTANCE Carefully remove high tension wires from spark plugs and distributor cap. Using an ohmmeter, measure resistance of wires while gently twisting wires. If resistance is not to specifications, or fluctuates from infinity to any value, replace high tension wire(s). HIGH TENSION WIRE RESISTANCE High Tension Wire Routing For high tension wire routing, see Fig. 2 and Fig. 3 . Fig. 3: Locating High Tension Wires On Distributor Cap Courtesy of MAZDA MOTORS CORP. ADJUSTMENTS DISTRIBUTOR All models are equipped with Mitsubishi electronic ignition with 2 pick-up coils. Air gap is non-adjustable IGNITION TIMING 1. Warm engine to normal operating temperature. Connect a tachometer, then connect timing light to leading (lower) spark plug of front rotor. Start engine and run at idle speed. 2. Check ignition timing and rotate distributor to correct if necessary. Tighten distributor lock nut and recheck timing. 3. Connect timing light to trailing (upper) plug of front rotor. Start engine and check timing. If not correct, loosen vacuum unit attaching screws. Move vacuum unit in or out to adjust trailing timing. Remove test equipment.

1993 Ford Crown Victoria V8-281 4.6L SOHC Engine – Lean Driveability Symptoms Manual

1. Look at the BARO PID. Refer to the Barometric Pressure Reference Chart in this article. At sea level, BARO should read about 159 Hz (29.91 in. Hg). As a reference, Denver, Colorado at 1524 meters (5000 ft.) altitude should be about 144 Hz (24.88 in.Hg). Normal learned BARO variability is up to +/- 6 Hz (+/- 2 in. Hg.). If BARO indicates a higher altitude than you are not at (7 or more Hz lower than expected), you may have MAF contamination. If available, Service Bay Diagnostic System (SBDS) has a Manifold Absolute Pressure (MAP) sensor that can be used as a barometric pressure reference. Use “MAP/BARO” test under “Powertrain,” “Testers and Meters.” Ignore the hookup screen. Connect GP2 to the reference MAP on the following screen. 2. On a fully warmed up engine, look at Long Term Fuel Trim at idle, in Neutral, A/C off, (LONGFT1 and/or LONGFT2 PIDs). If it is more negative than -12%, the fuel system has learned lean corrections which may be due to the MAF sensor over-estimating air flow at idle. Note that both Banks 1 and 2 will exhibit negative corrections for 2-bank system. If only one bank of a 2-bank system has negative corrections, the MAF sensor is probably not contaminated. 3. On a fully warmed up engine, look at MAF voltage at idle, in Neutral, A/C off (MAF V PID). If it’s 30% greater than the nominal MAF V voltage listed in the Powertrain Control/Emissions Diagnosis (PC/ED) Diagnostic Value Reference Charts for your vehicle, or greater than 1.1 volts as a rough guide, the MAF sensor is over-estimating air flow at idle. 4. If at least tow of the previous three steps are true, proceed to disconnect the MAF sensor connector. This puts the vehicle into Failure Mode and Effects Management (FMEM). In FMEM mode, air flow is inferred by using rpm and throttle position instead of reading the MAF sensor. (In addition, the BARO value is reset to a base/unlearned value.) If the lean driveability symptoms go away, the MAF sensor is probably contaminated and should be replaced. If the lean driveability symptoms do not go away, go to the PC/ED Service Manual for the appropriate diagnostics.

2003 GMC Truck C 1500 P/U 2WD Engine Knocking or Lifter Noise

The distinguishing characteristic of this condition is that it likely will have been present since new, and is typically noticed within the first 161-322 km (100-200 mi). The noise may often be diagnosed as a collapsed lifter . Additionally, the noise may be present at cold start and appear to diminish and then return as the engine warms to operating temperature. This noise is different from other noises that may begin to occur at 3219-4828 km (2000-3000 mi). Cause The 0-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil. Correction
