Service modifications have been developed to convert sea level calibrations for improved function at altitude (4,000 ft. and above). On a customer inquiry basis, employ the appropriate following procedure.
All Manual Transmissions
1. Remove air cleaner assembly and set aside.
2. Remove air cleaner bail retaining pin by using a pliers with a firm grip, to disengage light pin areas.
3. Remove air cleaner bail.
Figure 2:
4. Unscrew the primary high speed air blend, main well tube and main jet assembly (Figure 2).
NOTE:
The MMJ assemblies are staked in production. A moderate amount of resistance may be incurred when removing the MMJ assemblies; In addition, care should be taken in order to prevent any chips from entering the main well.
5. Using a thin needle nose pliers, carefully lift the assembly out of the carburetor.
Figure 3:
6. The high speed air bleed, main well tube and main jet are press fit assemblies and can be taken apart by hand (Figure 3).
7. Replace the primary high speed air bleed identified by the number 175 stamped on air bleed with the new air bleed stamped 200 (contained in Kit No. E2PZ-9D544-J).
8. Apply one drop of Ford Spec ESE-M4G-204-A3 (Loctite 262 or equivalent) on the threads of the MMJ assembly. Install and torque to 2.0 Newton meters or 17 in.-lbs.

If difficulty is incurred with installing MMJ assemblies, refer to TSB 82-4 for alternative installation procedure.
9. Unscrew the secondary high speed air bleed, main well tube and main jet assembly (Figure 2).
10. Using a thin needle nose pliers, carefully lift the assembly out of the carburetor.
11. Replace the secondary high speed air bleed identified by the number 150 stamped on air bleed, with the new air bleed stamped 200 (contained in Kit No. E2PZ-9D544-J).
12. Apply one drop of Ford Spec ESE-M4G-204-A3 (Loctite 262 or equivalent) on the threads of each MMJ assembly. Install and torque to 2.0 Newton meters or 17 in.lbs.
13. Install air cleaner bail and retaining pin.
14. Check and reset, if necessary, all idle speeds as per 1982 Car/Truck Shop Manual Engine/Emission Diagnosis Book I, Section 4, 4-15 thru 18, Carburetor Systems.
15. Install the air cleaner assembly.
16. Install a Ford Modification Decal adjacent to the Emission Control Information Decal listing high speed air bleed changes.

14. Check and reset, if necessary, all idle speeds as per 1981 Car/Truck Shop Manual - Engine/Emission Diagnosis Book I, Section 4, 4-15 thru 18, Carburetor Systems.
NOTE:
Whenever it is required to increase idle speed by more than 100 RPM. or for any decrease in idle speed, the automatic transmission throttle linkage must be readjusted using the procedure described in Part 17-25, Escort/Lynx Powertrain and Predelivery Manual.
15. Install air cleaner assembly.
16. Retain an Authorized Modification decal and list the date, dealer number and alterations performed as shown below.
