hey fellas, i'm trying to adjust the timing on my 1990 integra. instructions say to jump the ecu connector. i have done this before on my 1998 integra and it worked fine, the CEL light stayed on as it should. but when i do the same on the 90, the CEL light just turns off normally even thought the connector is jumped using a paperclip. any ideas? am i doing this correctly?

 

yea, the light CEL light doesn't stay on on obd0 ecus when you jump the connector
