I have honda civic 1992 and the check engine light came on went to auto shop he said problem in distributor than I buy used distributor from junkyard and replaced but after 2 day light came on again. Went to auto shop they said problem in distributor. Some time my car won't start it start but after 2 sec off than I have to wait for 15 mint then start fine in one click. Please tell me the problem.

What exact code was most recently thrown?

Code 9

Code 9 = Cylinder Position Sensor (CYP). Internal distributor sensors are not serviceable.

You will need to replace the distributor housing (genuine Honda only). Over 50% of new aftermarket distributors for Hondas, at AMHD, have not worked. The others have not been real reliable. To save money, replace the ICM and coil in the new housing:

No offence but that's why you buy quality used parts or brand new parts not ones from a junkyard
