I have an idling problem and the cel code toss a number 14(electronic air control). How do i fix this? It also tosses another code 91 (fuel tank circuit ). I don't know what this one does except for that it build pressure in my gas tank/cap. Can anyone explain to me what these are and how to fix it.

 

Could be a connection problem between the IACV and the ECU or a problem at the ECU pin for the IACV.

 

i thought it would be the fast thermo idle valve. How would the ecu pin be a problem? I'm not trying to offend you but i just want to know.

 

I think the other code(91) is the "gas cap" code, it would take three successful trips to reset that code, after you reset the ECU. You might have lost pressure at the gas cap.

I would like to know what do you mean by "three successful trips". Sorry i'm, a noob

 

I think that the cel 14 would have to be the iacv or the distributor?? Any second opinions?? And cel 91 is out there...I can't seem to think of anything except that if the wire is loose or fried...Any second opinion on that??

 

clean out your IACV first.
