Vehicles equipped with ATX transmissions which exhibit surge during moderate to heavy acceleration can be serviced by modifying the vacuum signal to the carburetor duty cycle solenoid.

1. Drive the above subject vehicle to verify the concern.
2. Perform EEC IV Diagnostics (QUICK TEST), if system is O.K., proceed to Step 3.

Figure 16:

3. Locate the 5/32 (black with red stripe) vacuum hose to the vacuum reservoir. This hose is routed along the right hand fender apron between the shock tower and the radiator overflow bottle (Figure 16).
4. Cut the hose and install (2) connectors (383003-S) and (2) caps (382444-S) at each end (Figure 16).
5. Secure both cut ends of vacuum hose to ensure access for possible future service requirements.
6. Perform a 3-mile drive (from a stop, accelerate to 55 mph with light, medium and heavy acceleration) to verify the above concern has been alleviated.
7. If drive concern still persists, replace carburetor. Do not reconnect vacuum hose.



Obtain an Authorized Modifications decal and list the date, dealer number and summary of alterations performed.
