Emissions Recall 90E90
Check
the Ford website &/or
the NHTSA to see if your VIN is affected.
Ford Motor Company is voluntarily recalling (Emissions Recall 90E90) certain 1987, 1988, and 1989 Model 4.9L California engine equipped F-Series and Bronco trucks. Your truck's engine may be releasing air pollutants which exceed California standards. This service should have little or no effect on your truck except to reduce air pollutants. If you do not have this service done, your emission warranty may be reduced. Also, your truck may not pass emissions or smog tests that may be required in your area.
What the Dealer Will Do
At no cost to you, your Ford dealer will replace the electronic engine control processor and adjust the ignition timing on your truck according to the instructions provided by Ford.
How Long Will It Take?
The time needed to repair your truck is approximately one hour. However, due to service scheduling times, your dealer may need your truck for one full working day. Call your dealer without delay. Ask for a service date and if parts are in stock. If your dealer does not have the parts in stock, they can be ordered before scheduling your service date. Parts would be expected to arrive within a week. When you bring your truck in, give the dealer this letter. If you misplace this letter, your dealer will still do the work, free of charge. If the dealer doesn't make the repair promptly and without charge, you may contact the Ford Parts and Service Division by calling 1-800-392-FORD.
Involved Vehicles: All 1987 / 88 / 89 - Model California F-150/250 and Bronco trucks equipped with manual transmissions and 4.9L having calibration 7-51R-R00.
Modification Kit Installation Instructions
1. Replace the existing electronic engine control processor with the new processor (Part number E8TZ-12A650-AAB) provided in kit.
2. Reset the initial ignition timing from 10 degrees to 7 degrees BTDC.
3. Important Electronic Engine Control (EEC) Processor Engine Idle Adaptation: The new processor will have to adapt to the sensors that provide it information.
a) With the engine running and the transmissions in neutral, increase the engine speed to 2,500 RPM and hold for two minutes.
b) Let the engine return to idle.
c) Increase the engine speed to 1,500 RPM, then let it return and remain at idle for 45 seconds. Repeat this step four times.
4. With the "Sharpie" marking pen provided in the kit, mark the Vehicle Emissions Control Information (VECI) decal to show that the initial timing was changed to 7 degrees BTDC (1987-Model Trucks also require marking the idle speed setting). Refer to the examples.
