initially I used the blink codes and got a code 9 - CYP.

disconnect battery, install new distributor, couple days later CEL back on.

wasted a few months trying to figure that out, only to find I was supposed to use a scanner to get the "p codes", not the blink codes

i took the car in since i dont have a scanner, the guy said it was P1457. he tested it and the evap purge valve was bad.

i got a new purge valve

disconnect battery, install new purge valve

guess what

CEL back on again

what now
