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. Testing, adjusting 1 Complete measurement sheet. 2 Switch off air conditioning or automatic climate control. Move selector lever into position “P”. 3 Read out DTC memory. Note: Not available on model year 1984-1986. 4 Connect testers: oil remote thermometer (018)124 589 07 21 00 lambda control tester (012) twin socket (031) trigger clamp (011) exhaust probe (005)126 589 11 63 00 CO measuring instrument (006) engine tester with oscilloscope (030) multimeter (003) test cable (033)102 589 04 63 00. 5 Position extraction device (014) at exhaust tail pipe. 6 Check engine coolant level, adjust to correct level. 7 Check engine oil level, pay attention to condition of oil (visual inspection). 8 Take off air cleaner. 9 Check ease of movement and condition of throttle control linkage and throttle valve. Grease all bearing points and ball sockets. 10 Check fulcrum lever, adjust. Check whether the roller (15) in the fulcrum lever (13) is resting free of tension against end stop. 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. Specification: 12.2 volts . Ignition coil Switch on ignition with engine not running. Test the voltage terminal 15 to ground at contact 5 of diagnostic connector. Specification: battery voltage Test difference in voltage between terminal 15 and terminal 1 at contacts 5 and 4 of diagnostic connector. Specification: 0 volts If the specified values are not reached, test

1986 Ford Truck F 150 2WD Pickup Emission Maintenance Warning Module-Service Manual

EMISSION MAINTENANCE WARNING MODULE SERVICE INFORMATION ^LAMP – “EMISSIONS/CHECK ENGINE” – EMISSION MAINTENANCE WARNING MODULE – SERVICE INFORMATION LIGHT TRUCK: 1985-89 BRONCO 1985-87 BRONCO II 1985-89 ECONOLINE, F- 150, F-250, F-350 1985-88 RANGER 1986-87 AEROSTAR ISSUE: The Emission Maintenance Warning “EMW” module operates a light that is located on the instrument panel. For 1985-87 model year vehicles, the light will display the word “EMISSIONS”. For 1988-89 model year vehicles, the light will display the words “CHECK ENGINE”. When the light is lit, it is indicating that the 60,000 mile emission maintenance should be performed. After the maintenance is performed the EMW module must be reset to zero time. Another type of module is the “IMS” module. This module is not part of the light circuit and does not require maintenance. At a predetermined time, the IMS module directs the EEC IV processor to make a strategy change. A third type of module is the “COMBO” module. This module combines the functions of the IMS and the EMW modules. ACTION: Refer to the following module application charts for the specific vehicle application and location of the different types of modules. NOTE: FOR APPLICATIONS NOT LOSTED IN THE FOLLOWING MODULE APPLICATION CHARTS, THE “CHECK ENGINE” LIGHT IS CONTROLLED BY THE EEC IV PROCESSOR. THESE VEHICLES DO NOT USE THE “EMW” MODULE

1994 Chevy Truck C 1500 Truck 2WD Tune-up and Engine Performance Checks/ Ignition-Timing Connector Location Change Manual

SUBJECT: TIMING CONNECTOR LOCATION CHANGE MODELS: 1994 CHEVROLET AND GMC C/K TRUCKS WITH GASOLINE ENGINES The timing connector, which can be disconnected to return engine timing to base for adjustment purposes, has been moved from the engine compartment to inside the cab. This new location is not currently reflected in the Service or Owner’s Manual. The new location is under the dash directly below the glove compartment. The tan/black wire is routed for a short distance outside of a large wiring harness. This large harness is routed between the heater blower motor and evaporator case. The timing connector is taped to the wire bundle (Figure 1)


NOTE: Please refer to Edelbrock Performer Series Carburetor Owner’s Manual for detailed tuning procedures. 1. Due to design, the fuel/air mixture and cylinder charging are very efficient with the CH-6B intake manifold. Generally speaking, the stock jetting for the recommended aftermarket carburetors will not need changing. Specific applications may show an increase in performance through further tuning. 2. Aftermarket distributor curve kits may be used with this intake manifold. 3. Use modified or high performance cylinder heads such as our Performer RPM. 4. The compression ratio should be at least 9.5 to 1 to work properly with Performer RPM camshafts. 5. Installation of aftermarket headers, camshafts or both may lean carburetor calibration. Should this occur, recalibrate with a richer jet INSTALLATION: 1. Use only recommended intake gaskets set when installing this intake manifold. 2. Fully clean the cylinder head intake flanges and the engine block end seal surfaces. 3. Use a factory style valley pan along with the recommended gaskets. 4. Apply Edelbrock Gasgacinch sealant P/N 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow to air dry, and attach the intake gaskets. 5. Install the intake manifold and hold-down bolts. Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 25 ft/lbs.
