Help, Low Idle :S Honda civic 95 EX
my car has a little problem and i need a little help pls.
when my car start in cold it runs fine, idle is good when is cold and A/C off.
if i turn on the A/C the rought low idle appear, if i turn off the A/C and the car still cold it runs fine, when it get the operating temperature the low idle come again no matter if the A/C is On or Off..
i have changed FITV, EACV, TPS, New P08 ECU, No CEL, cheked and Good PCV, and i dont know what more to do
i need a little help here pls

Re: Help, Low Idle :S Honda civic 95 EX
yesterday i checked my pcv it looks fine and the air pass through very fine, about the idle speed When loosening the screw only slightly increases :S and reaches a point where it not rises above, i will check the FAQ and see if i doing something wrong

hi, me again..
i do all the procedure of the ajusting idle speed and nothing the low idle still there... even the screw is almost completely loosen

hi thx for the response..
yes, i calibrate the TPS, 0.5 closed and 4.8 WOT,
about the ECT i dont have checked that, i will verify it tomorrow, there is a way to test it?.
about timing I never changed that, I guest must be well. the only way to check the time is using a timing light right? o there is another way?

The resistance of the ECT sensor should 200-400 Ohms when the engine is fully warmed up.
You may find a free rental on a timing gun at an auto parts store. You can buy a new one for about $30.

hi,
I had to go out and see the ETC Sensor hehehe, i do a visual inspection i see 2 splited wires, the plug has blk/ylw wire and red/blk wire.
and has tied, white/gree to blk/ylw and red/white to red/blk..
From ECU To ECT
------White/Red-------|---blk/ylw
-----Green/White------|---red/blk
White/Red and Green White are the correct wires color from the ECU to ECT?

1) Spliced wires should be soldered and insulated with shrink wrap. Your wires can short out on the engine.
2) You have the ECT sensor wires spliced to a connector with Yel/Blk and Red (or Red/Blk) wires, which fit with the EVAP purge solenoid not the ECT sensor.

Re: Help, Low Idle :S Honda civic 95 EX
my CEL is clear.. i don have any CEL.. the problem is with the idle.. :s i will test the sensor in the morning.. the time here is 1:06AM heheheh, so i will Measure resistance of the ECT sensor and check id the sensor is between 200-400 Ohms full warm engine.. if the sensor is out of that spec is bad right?

Can you post pictures of your engine and harness? If your ECT wiring looks like that more than likely you have some other "rigged" items that may be causing the issue.

Hii, me again..
i did the test of the ECT sensor.. i measured resistance between the 2 wires and my tester gave me 178 OHMS - 180OHMS.. i start the car and let it warm, when the fan turn on, turn of the car and check and that was the read 178 - 180 OHMS
