okay I just replaced my plugs in my 1990 civic now it wont start im getting code 14 which is EACV where should i go from here should a buy a new ECU or EACV??

 

are you sure your firing order is correct? did you maybe crack a plug putting them in?

 

ya firing order shouldnt have changed i pulled one wire out switched plugs put the same wire back i dont think i cracked one i didnt put em in too tight maybe ill put the old ones in and see if it starts

 

Unplug the IACV. Do you measure 8-15 Ohms across the two terminals of the sensor?

 

i will check when i get my hands on an ohm meter lol. anyone have a pic of where the eacv is on a 1990 civic cx

 

 

pulled the eacv today and gave it a good cleaning it was very dirty now its running better but still idling a little rough. I bought another complete intake manifold today with the throttle body and eacv intact for $5 today so im gonna check the ohms across each eacv and try this other one see if it make a diff.
