hi guys.

today my car got a idble problem, it has fluctuating idle, with the engine running any cel but when connect the jumper for service the code 14 blink on my CEL, any idea?

 

Reset the ecu see if its still there. If it is try cleaning your iacv. Search how

 

i already clean the iacv, i was checking the wire harnnes cuz, sometimes when the fluctuating idle happen moving the wires fluctuatig idle disappear, there is a way for wiring a paralel line to see the iacv behavior?

 

You MUST provide all pertinent information about your car and engine. Failure to do so may result in thread closure.

 

oh sorry, my car is an Civic 95 ex Coupe, engine D15b Vtec (swap, original was D16z6), automatic P08 ECU

 

So your saying when you mess with the wires it goes away?

 

IACV wires?

Also, click the FITV link in my signature.

 

yes, sometimes goes away sometimes not

 

yes, IAVC Wires.

i do the service manual procedure for the code 14 and all seems to be good, but when start the engine idle start on 1200 rpm, and then slowly goes down below 500 rpm, when the engine is at operating temperature and disconnect the iacv nothing happen, but when connect it again you can hear the click sound, idle goes up for a moment and then goes down again.

if you rev up the engine and then let in idle again, the fluctuating idle appear

 

Is the coolant level low in the radiator? Have you tried bleeding the cooling system?
----------

Bleeding the cooling system may take 20-30 minutes.

1) Park the car on an inclined driveway with the front end higher than the rear.

2) Push the dash heater lever/**** to MAX heat.

3) Follow the directions in the diagram below (hint: the bleed bolt is located where the upper radiator hose connects to the engine):

 

Sounds like a wiring problem

 

i do that yestarday, no air in the coolant system. now i was trying connect the pin A9 direct to the IACV with another connector and the idle is good, the only thing is when slowly press the gas the engine fails, sound like fluctuating but only when press the gas slightly

 

can i wire a paralel connection? if i can, how can i do it

 

I just have to connect a pin to 12 volts and the other to a9?

 

fluctuating idle solved, moving the TPS from 0.5v to 0.6, i dont know why
