i just did a b16a swap into my 89 ef and i'm getting a code 14 IACV,when i unplug it the idle gets rougher,therefore it's still good, also when i accelerated the car it redlines like at 3500-4000 and won't pass that,also i'm running a VAFC,would that have an effect on it? what could cause it to rev so ruff? any one with info i would appreciate it TONS!!!!!!!!!

 

backwards with the tps or some other similar plug

 

Could be a dirty IACV. Take it off to check and clean it with some carb cleaner while you're at it.

 

code 14 means no electrical conection on the iacv
check it with a ohm meter should be aound 40 ohms or so i think if its like 600 som wack o number or nothing its fried most likely it your wires i never came across a burnt out iacv they just dont go.. they clog up and get dirty yes..

 

ok thanks for the reply guys,but another question is qhat are the color wires going to the IACV for 89 ef,if anyone would happen to have that info : ),i maybe have the wrong plug in it!!!!

 

would the VAFC have any effect on it??

 

on my 89 crx i have a blue w/ yellow stripe and black with yellow stripe.
