Hi all

My rx-7 fd3s idle super rich 10.1 AF ! How can I settle this problem

Thanks in advance

 

turn it off

 

How to turn off ? I see many fd also have this problem !You can help me?

 

Are you on stock ecu?

Sent from my DROID RAZR using RX7Club

 

Vacuum line to MAP sensor plugged in?

Dale

 

Yes stock ecu !

 

+1

 

power fc have one also this problem ! Now no use again !

 

Hi my car is 1992 fd3s AT ! My car is all original my car idle super rich an many black smoke low speed very lag . I change spark plug ,plug carble ,map sensor ,coil ,fuel pump ,fuel filter ,air filter ,air temp sensor ,water temp sensor ,fuel temp sensor ,manual gearbox ,throttel body ,V mouth ,vaccum hose ,dash pot , Purge Control valve ,tps sensor ,BAC valve , fuel injector ,fuel regulator ,ground clable ,spark VSD aslo cannot settle now idle up down up down connect GND to TEN idle no difference ! Who can help me ? Thanks !

 

What do you mean connected the gnd and ten? If I'm not mistaken that's to check for ecu error codes,wouldn't do anything for idle....... We need more info, what was the last major or tune up type of thing have you done? I had similar issue at first with my power fc but was able to take away some fuel where my car would normally idle.

 

I had the same problem and i turned out to be my primary coils were bad. The poor car was only running on the secondaries. Also the car felt sluggish, either way I've check for spark.

 

How to check coil ? I use ohm meter is ok !

 

Now no use power fc ! Is stock ECU my power fc no commander .Use the gnd and ten setting the idle adjustment . The lower idle speed stated in the workshop manual only applies when you connect the TEN and GND terminals in the diagnosis connector - in other words when you adjust the idle speed. Connecting TEN and GND is necessary to temporarily disable the ISC (Idle Speed Control) system. When you set the idle speed to approx. 725 rpm using this method, it will jump to 850 the moment you pull the TEN-GND jumper!

 

 

+ apexi neo can ?

 

Oh, you know what, I had a problem with a pulsing idle like that for a while. What happened is the power FC was tuned with the AWS valve disconnected. I, like an idiot, reconnected it at one point and had a high reving pulsing idle. Check to make sure your electronics are right

 

Bro my car not this AWS valve!

 

The fuel rich is fd3s very normal problem?

 

That is running very rich. Who tuned it?
Have you opened the sensor check screen in the hand controller and checked that all sensor signals are as they should be? Oxygen sensor wire connected and unbroken? TPS online and adjusted correctly? Coolant sensor OK?
There's a bunch of things that could contribute to this. You'll have to work through the options one by one.

Very colorful car you have there... Silver vacuum chamber tank is pretty groovy man :p

If everything checks out sensor-wise, and its just a poor tune, you need to go back to a dyno and get it tuned properly.

Also, can we get some specs on what has been done to the car- is it stock sequential system, PFC, how many miles on this engine, etc.. Just some more info to try and help you and understand your situation a bit more.

 

Now use stock ecu all sensor i check is ok . The idling up down up down remove the idling valve also up down up down ! What will cause the idle time is that?

 

Bro the silver vacuum chamber tank is use the Aluminum cut and glue

 

The stock exhaust pipe have a one sensor now i change the exhaust the sensor want install back or not ?

 

Yes, you need that sensor. That exhaust sensor is the oxygen sensor. Put it back..

You also cant run the sensor check on the stock ECU. You must use the Power FC's Hand Controller to see all the sensors together and see if they are giving you signals or not.

Dont worry about the idle valve for now. Get your exhaust oxygen sensor back in the car and see what happens

 

Check your clutch switch. A bad clutch switch will cause pulsing idle.

 

Bro my car is auto replaced to manual not clutch switch!
