Need TSB #92041
Hi everyone. I was wondering if anyone has a copy of TSB 92041 that I can have. It deals with 1991 Civic failing emission testing and what to do about it. If anyone knows where to get it for free besides paying for it at Alldata, let me know thanks.

GENERAL
Vehicle Fails State Inspection and Maintenance Emission Test
SYMPTOM
Some vehicles with properly functioning emission control systems may fail certain states' tailpipe emissions test.
PROBABLE CAUSE
The following conditions may cause the car to exceed the state standards:
^ The vehicle is not fully warmed-up.
^ The idle period is too long.
^ The engine is shut-off, hot-soaked and restarted.
^ The underhood ambient temperature is very high.
NOTE:
All Honda automobiles do meet the U.S. E.P.A. and California emission standards when tested under the E.P.A. certification test procedure.
CORRECTIVE ACTION
Do the following before conducting the tailpipe emissions test.
The emissions test should be performed with the car at normal operating temperature. Before testing be sure the car has been driven for several miles at 25 mph or above, and test the car as soon as possible after driving.
1. Keep the engine at operating temperature (the cooling fan has cycled on and off twice).
2. To normalize the system, raise the engine speed to above 3500 rpm and allow the throttle to snap closed to idle.
