ok ok now i got it here try these. 1,14,5 ? how about those....

 

What year Civic?

 

Whenever you have more than one code, clear them and then see which one reoccurs first. That one probably corresponds to a real problem.

Note that code 14 will occur whenever the idle speed is out of control, which may or may not be due to the EACV itself.

 

ya i cleared it all and then started it back up and now its just saying 14. yeah... o by the way its a 99 civic with a 0bd1 motor. 94 delsol block 99 y8 head...

 

Are you sure that the Y8 IACV is compatible with the OBD1 ECU?
