I just installed a power FC and now my car stalls as I am driving it, when I go to slow down the RPM's drop and the car turns off, any one know how to fix this?

 

Assuming: the car idled correctly befor the PFC was installed, it was installed correctly, nothing else was changed at the same time and since then.

Make sure you idle parameters are set up as mentioned in the manual and that the different PFC functions are set up correctly.

Then if the problem is still there, adjust your idle like you would before you got the PFC. Throttle set and air bleed screws.

You might also need to check the TPS voltages and reset the(crap I can't think of it's name, the plunger thingy that slows down the closing of the throttle).

 

Yeah the car idles and runs perfect on the stock ECU, I set the idle with both ecu's but it still does the stalling. I will try to check the tps voltages but I am not sure where they are supposed to be. Thanks for the help.

 

You might need to find someone with PFC experince to look at your settings.

You might also have a bad PFC. My PFC was bad as it would not accept PFC changes. I sent them both back and when I got the replacements, the commander was my old one but the PFC was new.

 

did you cut the wires, pm me and i can take a look at it for you

 

Mine likes to stall once in a while... it has gotten better that I have played with the idle but it still isn't 100% gone. I was looking to replace my fuel filter and see if that helps.

 

whenever it wants to stall just rev it a few times. i had to do that a few times and havent had it happen since

 

I have had a few stalls too ... I am at a loss to say what / why ...

Sit for a few minutes, then it runs fine. I plan to check TPS & idle stuff.
